Question

12% of a number exceed 8% percent of the number by 20 the number is

Answer 1

$<b>$

Let Number be x

12%of x = 8% of x + 20

=> (12/100)×x = (8/100)x + 20

=> x[(12/100)-(8/100)] = 20

=> x(4/100) = 20

=> x/25 = 20

=> x = 25×20 = 500

The Number is 500

Answer 2

Let the required number be x

12% of a number = $\dfrac{x × 12}{100}$

8% of the same number = $\dfrac{x × 8}{100}$

12% of a number exceed 8% percent of the number by 20.


According to the question,

$\dfrac{x × 12}{100}$ = $\dfrac{x × 8}{100}$ + 20

➾ $\dfrac{12x}{100}$ = $\dfrac{8x}{100}$ + 20

➾ $\dfrac{12x}{100}$ - $\dfrac{8x}{100}$ = 20

➾ $\dfrac{4x}{100}$ = 20

➾ 4x = 20 × 100

➾ 4x = 2000

➾ x = $\dfrac{2000}{4}$

➾ x = 500




∴ The number is 500
