There were some persimmons, pears and kiwis. The number of persimmons was two times the number of pears. The total number of persimmons and pears was half of the number of kiwis. There were 153 fruits altogether. All the kiwis were sold at 6 for $12. How much money was collected from the sale of the kiwis?
Number of pears = 1 u
Number of persimmons = 2 u

Total number of pears and persimmons
= 1 u + 2 u
= 3 u

Number of kiwis
= 2 x 3 u
= 6 u

Total number of fruits
= 1 u + 2 u + 6 u
= 9 u

9 u = 153

1 u = 153 ÷ 9 = 17

Number of kiwis sold
= 6 u
= 6 x 17
= 102

Number of sets of 6 kiwis
= 102 ÷ 6
= 17

Amount collected from the sale of kiwis
= 17 x 12
= $204

Answer(s): $204
