Correct option is A
Given: 9 : 50 :: 20 : ?
Logic: (1st number 5) + 5 = 2nd number
For, 9 : 50
9 5 = 45, 45 + 5 = 50
Similarly,
20 : ?
20 5 = 100, 100 + 5 = 105
Thus, correct option is (a).

- 1)In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the pair in which the numbers are related in the same way as are the numbers of the following pairs.(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.)52, 8172, 101
