Will had some mangosteens and chikoos. The number of mangosteens and chikoos left were the same after Will sold
15 of the mangosteens and
57 of the chikoos. If he had 50 mangosteens at first,
- How many mangosteens were left?
- How many chikoos did Will have at first?

5x1 =
5 u |

After |
4x1 =

2 u |
(a)
Fraction of the mangosteens left
= 1 -
15 =
45 Fraction of the chikoos left
= 1 -
57 =
27The number of mangosteens and chikoos left were the same. Make the number of mangosteens and chikoos left the same. LCM of 4 and 2 is 4.
Number of mangosteens at first = 5 u
Number of chikoos at first = 7 u
5 u = 50
1 u = 50 ÷ 5 = 10
Number of mangosteens left
= 2 u
= 2 x 10
= 20
(b)
Number of chikoos at first
= 7 u
= 7 x 10
= 70
Answer(s): (a) 20; (b) 70
