Question

a number exceeds 20% by itself and by 112.find number ?​

Answer 1

Let the number be x.

According to question

x - x of 20% = 40

x - x * 20/100 = 40

x - x * 1/5 = 40

x - x/5 = 40

4x /5 = 40

x = 40*5/4

x = 200/4

x = 50

Hence, the number is 50.

Answer 2

Answer:

560

Step-by-step explanation:

let no. be x

given-

20% of x = 112         (as it exceeds by 20% and by 112)

so, 20/100 x x = 112

20x/100 = 112

20x = 112 x 100

20x = 11200

x = 11200/20

x = 560
