Question

Find the value of ‘A’ & ‘B’ from the following ?

$3A+25\underset{–}{}B2\underset{–}{}$

• A. A = 7, B = 5
• B. A = 6, B = 7
• C. A = 6, B = 6
• D. A = 7, B = 6

Answer 1

The correct option is D

A = 7, B = 6

Since, last digit of A + 5 = 2, A can take the value of 7 which gives 7 + 5 = 12, writing 2 and carrying 1 to the next column.

Then , B = 1 (carry) + 3 + 2 = 6
