Question

When 125 is subtracted from a number, it reduces to its 37.5 per cent. What is 25 per cent of this number
​

Answer 1

Answer:

Let the number be x.

According to the question,

x - 125 = 37.5 % of x

⇒ x - 125 = x * 37.5 / 100

⇒ x - 125 = 0.375 x

⇒ x - 125 = 0.375 x

⇒ x - .375 x  = 125

⇒ 0.625 x = 125

⇒ x = 125 / .625

⇒ x = 200

25 % of x = 200 * 25/100 = 50

So, 25% of the number is 50.
