Q:

What is 15 of 80 with simple method and examples?

A) 12.5% B) 18.75%

C) 16.55% D) 17.80%

A) 12.5%

B) 18.75%

C) 16.55%

D) 17.80%

Answer & Explanation Answer: B) 18.75%

Explanation:

Given that to find 15 of 80

=> What % of 80 is 15

Let it be 'p'

=> p% of 80 = 15

=> $\frac{p x 80}{100} = 15 \Rightarrow p = \frac{15 x 100}{80} \Rightarrow p = \frac{1500}{80} = 18.75$

Therefore, 15 is 18.75% of 80 => 18.75% of 80 = 15

Example::

Now, in the similar way we can find 15% of 80 =?

=> 15x80/100 = p

=> p = 4 x 3 = 12

Therefore, 15% of 80 = 12
