Question

A boy multiplies 987 by a certain number and obtains 559981 as his answer. If in the answer both 9's are wrong but the other digits are correct, then the correct answer will be :

Options:

A . 553681

B . 555181

C . 555681

D . 556581

Answer: Option C
Clearly, 7261 must be replaced by 2961,
which is possible if 6648 is replaced by 6218,
which in turn is possible if 5599 is replaced by 5556.
Thus, the correct number is 555681
