Harry had some mangosteens and lemons. The number of mangosteens and lemons left were the same after Harry sold
45 of the mangosteens and
35 of the lemons. If he had 120 mangosteens at first,
- How many mangosteens were left?
- How many lemons did Harry have at first?

(a)
Fraction of the mangosteens left
= 1 -
45 =
15 Fraction of the lemons left
= 1 -
35 =
25The number of mangosteens and lemons left were the same. Make the number of mangosteens and lemons left the same. LCM of 1 and 2 is 2.
Number of mangosteens at first = 10 u
Number of lemons at first = 5 u
10 u = 120
1 u = 120 ÷ 10 = 12
Number of mangosteens left
= 2 u
= 2 x 12
= 24
(b)
Number of lemons at first
= 5 u
= 5 x 12
= 60
Answer(s): (a) 24; (b) 60
