Question

What is 20% of 50% of 60% of 200?

Answer 1

Hint: To solve this problem first find 60% of 200 then find the 50 % of the number obtained and like this find the 20% of the number obtained. Doing this will solve our problem.

Complete step-by-step answer:
We know that p percent of q can be written as $\dfrac{{{\text{p}}\,{\text{x q}}}}{{{\text{100}}}}$.
So, 60 % of 200 is $\dfrac{{60\,{\text{x}}200}}{{100}}$= 60x2=120
And 50% of 120 can be obtained as $\dfrac{{50{\text{x}}120}}{{100}} = 5{\text{x}}12 = 60$
And 20% of 60 can be obtained as $\dfrac{{60{\text{x}}20}}{{100}} = 6 \times 2 = 12$.
So the answer to this question is 12.

Note: Whenever we face such type of problems of finding percentage of a given number then we need to know that p percent of q can be written as $\dfrac{{{\text{p}}\,{\text{x}}\,{\text{q}}}}{{{\text{100}}}}$. Proceeding like this will solve our problem and give you the right answer.
