Question

when 40 is subtracted from a number it reduces to its 60% find 100%of the number?
​

Answer 1

number let x

From x we subtracted 35 so it reduced 80% of it

So equation is

x-35=x*80/100

now 80% is reduced from x, so x-4x/5=x/5

x-35 =x/5

5x-175=x

X=175/4

That no is 175/4 *4/5

Answer 2

Step-by-step explanation:

Let the original no. be x.

According to the question,

x - 40 = 60/100 * x

x - 40 = 3/5 * x

5x - 200 = 3x

5x - 3x = 200

2x = 200

x = 200/2

x = 100
