At a fruit stall, 384 mangosteens were sold in the morning and ⁵₈ of the remaining mangosteens were sold in the afternoon. As a result, the number of mangosteens left became ¹₄ of the total number of mangosteens at first. Given that the mangosteens were sold at $2.10 in packs of eight mangosteens, how much did the fruit stall receive from the sale of the mangosteens in the afternoon?
Fraction of the remaining mangosteens left
= 1 - ⁵₈
= ³₈

Make numerators the same.
³₈ of remaining mangosteens = ¹₄ of total mangosteens
³₈ of remaining mangosteens = ³₁₂ of total mangosteens

12 u - 8 u = 384
4 u = 384
1 u = 384 ÷ 4 = 96

Number of mangosteens sold in the afternoon
= 5 u
= 5 x 96
= 480

Number of packs of eight mangosteens sold in the afternoon
= 480 ÷ 8
= 60

Amount received for mangosteens sold in the afternoon
= 60 x 2.10
= $126

Answer(s): $126
