Question

A number becomes 80% of itself after reducing 27 from it. Find 40% of that number.

Answer 1

Answer:

54

Step-by-step explanation:

Let x be the number.

Reducing x by 27 results in 80% of x

=> x - 27 = 0.8x = (4/5) x

=> x/5 = 27

=> x = 27 × 5 = 135

So...

80% of x = x - 27 = 135 - 27 = 108

=> 40% of x = 108 / 2 = 54
