Question 9

If the sum of the ratios equivalent to $$16\frac{2}{3}$$%, $$33\frac{1}{3}$$%, 5% and 25% is x% of 15, then x =

Solution

$$16\frac{2}{3}$$%=50/300.

$$33\frac{1}{3}$$%=100/300.

5%=5/100=15/300.

25%=25/100=75/300.

So, according to question:

(15/100)x=(50/300)+(100/300)+(15/300)+ (75/300).

(15/100)x=(240/300).

or,x=(240×100)/(15×300)=80/15=16/3.

A is correct choice.
