Smita was asked to multiply a certain number by 36. She multiplied it by 63 instead and got an answer of 3834 more than the correct one. What was the number to be multiplied?
Correct Answer: 142
Explanation:
Let us assume the certain Number is A.
According to question,
63A = 3834 + 36A
63A - 36A = 3834
⇒ 27A = 3834
⇒ A = 142
