n=(138×100)/92

n=1.5×100

n=150

Answer 2

Answer:

The number is 138.

Step-by-step explanation:

Given,

A number when decreased by 8% gives 138.

To find: The Number

Solution:

Let the number be x.

According to question,

x - 8% of x = 138

x - (8 / 100 )* x = 138

x - 8x / 100 = 138

(100x - 8x) / 100 = 138

92x = 138 * 100

x = 138 * 100 / 92

x = 150

Therefore, The number is 138.
