Analogy among words
Mother says, "What a cow is to milk, a hen is to an egg." A cow gives milk, a hen gives eggs. Spotting the link between two things and applying the same link to another pair is analogy.
Analogy is a question of the form "first : second :: third : ?". Find the link in the first pair and apply the same link to the third word to get the fourth. The sign "::" means "in the same way".
Links among words
| Link | Example |
|---|---|
| Work / use | Pen : writing :: scissors : cutting |
| Name of the young one | Cow : calf :: horse : foal |
| Place to live | Bird : nest :: honeybee : beehive |
| Sound | Dog : barking :: cat : meowing |
First say the link of the first pair in one sentence.
- E.g. Dog : barking. Link : a dog barks. So it is a link of sound.
Apply the same link to the third word.
- E.g. Cow : calf :: horse : ? The young one of a cow is a calf, so the young one of a horse is a foal.
See who lives or is kept where.
- E.g. Bird : nest :: honeybee : ? The home of a honeybee is the beehive.
A link can also be whole and its part.
- E.g. Week : day :: year : ? A part of a year is a month.
Dog : barking :: cat : ?
- A dog barks. This is a link of sound.
- A cat meows. Answer : meowing.
Bird : nest :: honeybee : ?
- A bird lives in a nest.
- A honeybee lives in a beehive. Answer : beehive.
School : headmaster :: district : ?
- The head of a school is the headmaster.
- The head officer of a district is the Collector. Answer : Collector.
Do not change the direction. The word that is first in the first pair must be first in the second pair.
Applying the link backwards. In "Cow : calf" the cow comes first and the young one second; for "Horse : ?" you need the young one, not the owner of the horse.
Memory clue : "Say the link in a sentence, apply it to the third."
If no link comes to mind, try the five link types one by one : work, young one, place, sound, part.

| Link | Example |
|---|---|
| Work | Eyes : seeing |
| Young one | Goat : kid |
| Place | Fish : water |

Analogy among numbers
If 1 pen costs Rs 5 in a shop, then 2 pens cost Rs 10. So the number of pens and the price have a link : the number is multiplied by 5. In pairs of numbers we find a link in the same way.
In number analogy there is a pair like "3 : 9 :: 5 : ?". Find what was done to the first number to get the second (adding, multiplying, squaring). Do the same to the third number.
Links among numbers
| Link | Example |
|---|---|
| Add / subtract | 5 : 8 (+3) |
| Multiply | 4 : 12 (× 3) |
| Square | 4 : 16 (4 × 4) |
| Cube | 3 : 27 (3 × 3 × 3) |
Find what was done to the first number to get the second : add, subtract, multiply.
- E.g. In 5 : 8, 3 was added. So 7 : 10.
Spot a square : multiply the number by itself.
- E.g. In 4 : 16, 4 × 4. So 6 : 36.
Spot a cube : multiply the number three times.
- E.g. In 2 : 8, 2 × 2 × 2. So 3 : 27.
Sometimes there are two operations : first multiply, then add.
- E.g. In 2 : 5, double and add 1. So 4 : 9.
4 : 8 :: 7 : ? (1) 14 (2) 12 (3) 49 (4) 21
- Double of 4 is 8.
- Double of 7 is 14. Answer : 14.
5 : 26 :: 7 : ? (1) 50 (2) 48 (3) 56 (4) 14
- 5 × 5 = 25 and 1 added = 26.
- 7 × 7 = 49 and 1 added = 50. Answer : 50.
3 : 28 :: 4 : ? (1) 65 (2) 36 (3) 48 (4) 80
- 3 × 3 × 3 = 27 and 1 added = 28.
- 4 × 4 × 4 = 64 and 1 added = 65. Answer : 65.
Once you fix the operation, try it on the other pair; check whether that answer is in the options.
Grabbing one operation in a hurry. In 3 : 9 both squaring and multiplying by 3 fit; take the operation that fits the options.
Memory clue : "Add, multiply, square, cube : easy first, then two operations."
If the first operation does not fit, think of two operations : multiply and add.

Analogy among letters
In a letter game if "A : C" is given then "E : G" follows, because we jump two letters ahead. Letters can be given numbers too : A = 1, B = 2, C = 3, so the link of letters can be found just like with numbers.
In letter analogy we see how far a letter moved forward or backward, whether it turned into its opposite, or whether the word was reversed. Do the same to the third.
Links among letters
| Link | Example |
|---|---|
| Moving ahead | B : D :: F : H (+2) |
| Opposite letter | C : X :: D : W (sum 27) |
| Reversed word | DOG : GOD :: PAN : NAP |
| One letter changed | BAT : BIT :: CAT : CIT |
Give the letters numbers (A = 1) and see how far it moved ahead.
- E.g. In B : D, 2 to 4, that is +2. So F : H.
Opposite letter : the two numbers add up to 27.
- E.g. In C : X, 3 + 24 = 27. So D : W (4 + 23 = 27).
See whether the word is written backwards.
- E.g. CAT : TAC. So DOG : GOD.
See whether the letter at one place was changed.
- E.g. In BAT : BIT, A was replaced by I. So CAT : CIT.
B : D :: F : ?
- From B (2) to D (4) : two ahead.
- Two ahead of F (6) is H (8). Answer : H.
C : X :: E : ?
- C (3) and X (24) : 3 + 24 = 27.
- For E (5) : 27 − 5 = 22, that is V. Answer : V.
CAT : DBU :: DOG : ?
- Each letter one ahead : C → D, A → B, T → U.
- D → E, O → P, G → H. Answer : EPH.
Write the numbers from A = 1 to Z = 26; the link of the letters shows through the numbers at once.
Looking only at the link of the first letter. Check that the same operation was applied to every letter of the word.
Memory clue : "Letter = number; ahead-behind, opposite, reversed word."
For an opposite letter subtract from 27; that is the answer.

| Same gap in numbers | Moving ahead or back |
| Numbers add up to 27 | Opposite letter |
| Same letters, reversed order | Reversed word |

Analogy among figures
Count the corners of a square roti and you get 4, of a triangular samosa 3. Figures have qualities like sides, corners and the sum of angles. We have to spot the link among them. Here the figures are given in words.
In figure analogy a quality of the first figure (sides, angles, the solid form) is given in the second place. Tell the same quality of the third figure.
Links among figures
| Link | Example |
|---|---|
| Number of sides | Triangle : 3 :: hexagon : 6 |
| Flat → solid | Square : cube :: circle : sphere |
| Sum of angles | Triangle : 180° :: quadrilateral : 360° |
| Lines of symmetry | Rectangle : 2 :: square : 4 |
Count the sides.
- E.g. Triangle : 3. So pentagon : 5.
Spot the solid form of a flat figure.
- E.g. Square : cube. So circle : sphere.
Sum of angles : split the figure into triangles, each 180°.
- E.g. Quadrilateral = 2 triangles. 2 × 180 = 360°.
Lines of symmetry : fold the figure and see in how many ways it makes two equal halves.
- E.g. Rectangle : 2, square : 4, equilateral triangle : 3.
Triangle : 3 :: hexagon : ?
- A triangle has 3 sides.
- A hexagon has 6 sides. Answer : 6.
Square : cube :: circle : ?
- The solid form of a square is the cube.
- The solid form of a circle is the sphere. Answer : sphere.
Triangle : 180° :: pentagon : ?
- A pentagon splits into 3 triangles.
- 3 × 180 = 540. Answer : 540°.
Make a habit of counting sides, corners and triangles; the answer shows at once.
Mixing up sides and triangles in the sum of angles. A pentagon has 5 sides but 3 triangles.
Memory clue : "Count the sides, make triangles, multiply by 180."
Triangles = sides − 2; so a hexagon makes 4 triangles.

Mixed questions and exam tricks
In the exam words, numbers and letters come together. "Calf : cow" and "cow : calf" have opposite links; if the direction goes wrong the answer goes wrong. So first say the link of the pair in a sentence.
To solve any analogy, first say the link of the pair in one sentence, then apply it to the third, and finally check it in the options. If two links fit, pick the one that is in the options.
List of all links
| Group | Links |
|---|---|
| Words | Work, young one, place, sound, part |
| Numbers | Add, multiply, square, cube, two operations |
| Letters | Ahead-behind, opposite letter, reversed word |
| Figures | Sides, solid form, sum of angles |
Say the link of the first pair in a sentence : "A is the ___ of B".
- E.g. Calf : cow. A calf is the young one of a cow.
Say the same sentence for the third and fourth.
- E.g. Puppy : bitch. A puppy is the young one of a bitch.
Check in reverse : read from the fourth word to the third.
- E.g. Foal : horse. A foal is the young one of a horse. The link is right.
If two links fit, pick whichever fits the options.
- E.g. 3 : 9 :: 5 : ? If both 15 and 25 are in the options, look at one more pair.
Calf : cow :: puppy : ?
- A calf is the young one of a cow.
- A puppy is the young one of a bitch. Answer : bitch.
Writer : book :: singer : ?
- A writer writes a book.
- A singer sings a song. Answer : song.
J : Q :: K : ?
- J (10) and Q (17) : 10 + 17 = 27, opposite letter.
- For K (11) : 27 − 11 = 16, that is P. Answer : P.
First say the link in a sentence; once the sentence is ready the answer is easy.
Changing the direction. "Calf : cow" and "cow : calf" have opposite links.
Memory clue : "Link in a sentence, same for the third, check in reverse."
After getting the answer, test it with the sentence "the fourth is the ___ of the third".
Spot the difference
| Mistake | Right way |
|---|---|
| Applying the link backwards | First : second as third : fourth |
| Looking only at the first letter | Apply the operation to every letter |
| Grabbing one operation | Check on the second pair |
