There were some lemons, mangoes and apples. The number of lemons was five times the number of mangoes. The total number of lemons and mangoes was half of the number of apples. There were 180 fruits altogether. All the apples were sold at 5 for $14. How much money was collected from the sale of the apples?
Number of mangoes = 1 u
Number of lemons = 5 u

Total number of mangoes and lemons
= 1 u + 5 u
= 6 u

Number of apples
= 2 x 6 u
= 12 u

Total number of fruits
= 1 u + 5 u + 12 u
= 18 u

18 u = 180

1 u = 180 ÷ 18 = 10

Number of apples sold
= 12 u
= 12 x 10
= 120

Number of sets of 5 apples
= 120 ÷ 5
= 24

Amount collected from the sale of apples
= 24 x 14
= $336

Answer(s): $336
