Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row: 73, 52, 75
Second row:64, 41, 63
Third row: 68, 47, ?
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. For example, 13 – Operations on 13 such as adding/deleting/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.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 69
The logic in the given series is:
First row: 73, 52, 75 = 73 + 52 = 125 × (3/5) = 75
Second row:64, 41, 63 = 64 + 41 = 105 × (3/5) = 63
Third row: 68, 47, ? = 68 + 47 = 115 × (3/5) = 69
Hence, the correct answer is 69.
