Question

If 11 is subtracted from 4 times a number, the result is 89. Find the number.

Answer 1

Let the required number be x.
According to the question:
4x −11 = 89
or, 4x − 11 +11 = 89 + 11 [Adding 11 on both the sides]
or, 4x = 100
or, `(4x)/4=100/4` [Dividing both the sides by 4]
or, x = 25
Thus, the required number is 25.
