Question

The digits correspond to the letters representing those digits in the given multiplication. Here D stands for ?

• A. $2$
• B. $3$
• C. $4$
• D. $5$

Answer 1

The correct option is C $4$

Observe row 3 of multiplication:

3 X C gives 1 in units place. So C = 7

( 3 X B ) + 2 gives 6 in units place

so 3 X B could be 24 . So B = 8

Observe row 2 of multiplication

5 X 7 (C) = 35

5 X 8 (B) + 3 = 43

9 X 5 +4 = 49 . So A = 9

Observe row 1 of multiplication

D X 7 gives 8 in its unit place so D is 4.

So option C.
