Find the missing number?

A. 2

B. 7

C. 1

D. 9

Answer: Option A

Solution(By Examveda Team)

Reading each row as a 3 or 2 digit number, subtract the central 2 digit value from the upper 3 digit value, to give the 3 digit result on the lower row. I.e.
239 - 97 = 142.
So, required Missing number is 2.
