Question

if 20% of a certain number is more by 12 than 12% of the same number, calculate the number​

Answer 1

Step-by-step explanation:

20% of 80 = 8 2 = 16

20% of 300 = 30 2 = 60

20% of 41 = 4.1 2 = 8.2

Answer 2

Answer:

No. is 150

Solution

Let the no X

Let's make an equation

20% of no X is more than 12 by its 12%

$x \times \frac{20}{100} = x \times \frac{12}{100} + 12$

$\frac{20x}{100} = \frac{12x}{100} + 12$

By transposing, we get

$\frac{20x}{100} - \frac{12x}{100} = 12$

$\frac{8x}{100} = 12$

By transposing 100 to RHS

$8x = 12 \times 100$

$8x = 1200$

$8x = 1200$By transposing 8 we get

$x = \frac{1200}{8}$

$x = 150$

Ans. Thus the certain no is 150.
