Question

if the difference between a number and one fifth of it is 84,what is the number?

Answer 1

Hiii friend,

Let the one Number be X.

One fifth of Number = 1/5 X = X/5.


According to question,

X - X/5 = 84

5X -X = 84 × 5

4X = 84×5

X = 84×5/4 = 21×5 = 105.


Hence,

Number = X = 105


HOPE IT WILL HELP YOU...... :-)
