3 girls share a number of apples in the ration 5:3:2. If the highest share is 40 apples, find the smallest share

A.
36 
B.
24 
C.
16 
D.
38
Correct Answer: Option C
Explanation
The sum, S of ratio is S = 5 + 3 + 2 = 10.
But highest share = (frac{5}{10} times T), where T is the total number of apples.
Thus, (40 = frac{5}{10} times T),
given 40 x 10 = 5T,
(T = frac{40 times 10}{5} = 80)
Hence the smallest share = (frac{2}{10} times 80)
= 16 apples
