Question

5. By what number must a given number be multiplied to increase it by 12%?​

Answer 1

Answer:

The number should be multiplied by 12/100

to obtain it's 12% and also you've to add it with the number to obtain 12% increase

an example is

Let increase 12% of 50

that is

$( \frac{12}{100} \times 50) + 50 \\ (\frac{12}{10} \times 5 ) + 50 \\ \frac{60}{10} + 50 \\ 6 + 50 = 56$

therefore 12% of 50 is 6

and for increasing, you've to add it with the real amount
