Question

find a number whose fifth part increased by 30 is equal to its fourth part decreased by 30.

Answer 1

THE CORRECT ANSWER IS 60

Answer 2

Let the number x.

The 5th and the 4th part will be  x/5 and x/4.

Given, 5th part and 4th part will be increased  and decreased by 30 i.e

(x/5) + 30 = (x/4) - 30

(4x - 5x)/20 = -60

-x = -1200

x = 1200.
