The average number of mangosteens in Container Q, Container R and Container S is 20 and it is 5 more than the average number of chikoos in the 3 containers.
15 of the chikoos are in Container Q and the chikoos in Container Q is 60% of the number of chikoos in Container R. If each container has the same number of fruits, what percentage of the fruits in Container S are mangosteens?
Average number of chikoos
= 20 - 5
= 15
Total number of chikoos
= 3 x 15
= 45
Total number of mangosteens
= 3 x 20
= 60
Total number of fruits
= 45 + 60
= 105
Number of fruits in each container
= 105 ÷ 3
= 35

35The number of chikoos in Container Q is repeated. Make the number of chikoos in Container Q the same. LCM of 1 and 3 is 3.
Total number of chikoos
= 3 u + 5 u + 7 u
= 15 u
15 u = 45
1 u = 45 ÷ 15 = 3
Number of chikoos in Container S
= 7 u
= 7 x 3
= 21
Number of mangosteens in Container S
= 35 - 21
= 14
Percentage of the fruits in Container S are mangosteens
=
1435 x 100%
= 40%
Answer(s): 40%
