answer is 4)169 refer image and it is question of NSO exam of aakash
The required number is 169.
Given:
234:81 :: 185:196 : :587:400 :: 283:?
To Find:
The number that satisfies the blank.
Solution:
In this question, we need to discover a logic or pattern that is followed by the first three pairs of numbers and apply it to 283 to obtain the required number.
By adding the digits to the left of ':' and taking its square, we obtain its corresponding number.
We observe that:
2+3+4 = 9
9² = 81.
⇒ 234:81
1+8+5 = 14
14² = 196.
⇒ 185:196.
5+8+7 = 20
20² = 400.
⇒ 587:400
Hence, the corresponding number of 283 is calculated by adding each of the digits in 283 and taking its square:
2+8+3 = 13
13² = 169.
⇒ 283:169
Hence, the correct answer is 234:81 :: 185:196 : :587:400 :: 283:169.
∴ The required number is 169.
