Question

When Raju multiplies a certain number by 17 and adds 4 to the product, he gets 225. Find that number.

Answer 1

Let the required number be x.
When Raju multiplies it with 17, the number becomes 17x.
According to the question :
17x + 4 = 225
or, 17x + 4 − 4 = 225 − 4 [Subtracting 4 from both the sides]
or, 17x = 221
or, `(17x)/17=221/17` [Dividing both the sides by 17]
or, x = 13
Thus, the required number is 13.
