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.
