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: 16
Explanation
The sum, S of ratio is S = 5 + 3 + 2 = 10. But highest share = 5/10× T , where T is the total number of apples. Thus, 40=5/10 × T, given 40 x 10 = 5T, T= (40×10)/5=80 Hence the smallest share = 2/10 × 80 = 16 apples
