NUMBER ANALOGY
Analogy means correspondence.
Introduction This section deals with two types of questions:
Example 1 : Find the missing term : 121 : 12 : : 25 : ?
(a) 1 (b) 2 (c) 6 (d) 7
Solution : (c) To find the missing term. Obtain the relationship as . As 121 is the square of 11. By adding 1 we get 12. Similarly, we can use this relation for next term: 25 is the square of 5. so answer is 5 + 1 = 6
Example 2 : Find the missing term: 5 : 124 : : 7 : ?
(a) 125 (b) 248 (c) 342 (d) 343
Solution : (c) To find the missing term. Obtain the relationship as . So, cube of 5 is 125. By subtracting 1 from 125, we get 124. Similarly, we can use this relation for next term: Cube of 7 is 343, By subtracting 1 , we get 342.
Example 3 : Find the missing term. 9 : 8 : : 16 : ?
(a) 27 (b) 18 (c) 17 (d) 14
Solution : (a) To find the missing term. Obtain the relationship as . So, if we take x = 3, y=2,
and
.
Similarly, we can use this relation for next term: , X = 4, Y = 2, X-1 = 4-1 = 3, Y+1 = 2+1 = 3 So, the answer is cube of 3 is 27.
Example 4 : Find the missing term: 16 : 27 :: 25 : ?
(a) 49 (b) 36 (c) 64 (d) 121
Solution : (c) In the given number analogy, first term is square of 4 and second term is cube of 3. Similarly, in case of third and fourth term. Third term is square of 5 and fourth term will be the cube of 4 is 64.
Similarly,
So, the answer is 64.
Example 5 : Select the pair in which the numbers are similarly related as in the given pair: 12 : 144
(a) 22 : 464 (b) 20 : 400 (c) 15 : 135 (d) 10 : 140
Solution: (d) The relationship is . So square of 12 is 144 and square of 20 is 400. So, correct answer is (b).
Example 6 : Select the pair in which the numbers are similarly related as in the given pair: - 11 : 1210
(a) 6 : 216 (b) 7 : 1029 (c) 8 : 448 (d) 9 : 729
Solution : (c) The relationship is So cube of 11 is 1331 and square of 11 is 121. 1331 - 121 = 1210. Similarly Cube of 8 is 512 and square of 8 is 64. 512 - 64 = 448. So option C is correct.
Example 7 : Complete the analogy: 144 : 23 :: 169: _____
(a) 34 (b) 42 (c) 24 (d) 25
Solution : So, its a tricky question. Lets start by analysing the relation between 144 and 23. So, 144 is square of 12, and number before 12 is 11. Adding 12 and 11 we get 23.
Similarly, apply this relation in next term: 169 is square of 13. and number before 13 is 12. Add 13 and 12 = 25. So option D is correct.

My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.
Ayan Ghosh
8thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
Hiya Gupta
8thAbhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.
Manish Kumar
10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
Shivam Rana
7thIt was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
Cheshta
10thIt has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
Barkha Arora
10thA marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
