Correct option is D
X : 289 :: 23 : Y
289 = (17)²
So, X − 10 = 17
X = 27
Y = (23 − 10)²
= 13²
= 169
X = 27, Y = 169
(D)
In the following number-pairs, the second number is obtained by performing certain mathematical operations on the first number. Which numbers should replace and so that the pattern followed by the two numbers on the left side of :: is the same as that on the right side of :: ?
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/ multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
X : 289 :: 23 : Y
Below are given two sets of numbers. In each set of numbers, a certain mathematical ope ration on the first number results in the second number. Similarly, certain mathe matical operation on the second number results in the third number and so on. Which of the given operations follows the same set of operations as in question? (NOTE - A two/three-digit number cannot be broken into individual digits for operations e.g. if 37 is followed by 10 , the operation cannot be 3+7 as a two-digit number cannot be broken into individual digits)
