Question

Digit 7 does not occur in the following multiplication. identify the digits represented by the letters.

What is the sum of the digits of the Product ?

• A. 21
• B. 23
• C. 29
• D. 25

Answer 1

The correct option is B 23

Observe the 3rd row of multiplication

3 X B = 3 so B = 1

Observe row 1 of multiplication

D X 2 + carry one = 5 so D = 2

F = 2 and O = 2

Observe row 2 of multiplication

C X A = 6 or 16

for C X A to be 6, A and C take value 6 and 1 respectively to meet the conditions but the multiplication brings 7 in the 3rd row. So we discard 6 and for 16

A = 8 and C = 2

Putting values accordingly,

we get values as given in above solved multiplication.

Sum of the digits of the Product $=9+0+4+8+2=23$

Hence, option B is correct.
