Download Solution PDFIn the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which numbers should replace X and Y 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 : 44 :: 72 : Y
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe logic followed here is:
Logic: (1st number ÷ 2) + 10 = 2nd number.
X : 44 :: 72 : Y
For value of X.
X : 44
→ (X ÷ 2) + 10 = 44
→ (X ÷ 2) = 44 - 10
→ X = 34 × 2
→ X = 68
Now for value of Y.
72 : Y
→ (72 ÷ 2) + 10
→ 36 + 10
→ 46.
Thus, value of X is 68 and value of Y is 46.
Hence, the correct answer is "Option 4".
