Question

20% of a number when subtracted from 108, gives
the number itself. Find the number.
​

Answer 1

Answer:

Let us assume the number as 'x'

91-(*x) = x

91-(3x/10)=x

x-91=-3x/10

x =  

10x = -3x+910

13x = 910

x = 910/13

= 70

Therefore x = 70

Answer 2

Answer:

The required number is 90

Step-by-step explanation:

Let the number be x

∴ 108 - x * 20% = x

or, 108 -  0.20 x = x

or, x + 0.20 x = 108

or, 1.20 x = 108

or, x = $\frac{108}{1.20}$

or, x = 90

∴ The required number is 90.
