A box contains some kiwis, apples and chikoos. 0.6 of the kiwis is equal to 80% of the apples. The number of chikoos is ³₅ of the total number of apples and kiwis. If there are 36 less apples than chikoos, how many fruits are there in the box altogether?

Kiwis	Apples	Chikoos
4x5	3x5
5x7		3x7
20 u	15 u	21 u

0.6 = ⁶₁₀= ³₅
80% = ⁸⁰₁₀₀ = ⁴₅

0.6 of the kiwis is equal to 80% of the apples. Make the numerators the same.  LCM of 3 and 4 is 12.

3x45x4 of the kiwis = 4x35x3 of the apples
1220 of the kiwis = 1215 of the apples 

Kiwis : Apples
20 : 15 _(÷5)
4 : 3

The total number of kiwis and apples is repeated.  Make the total number of kiwis and apples the same.  LCM of 7 and 5 is 35.

Number of less apples than chikoos
= 21 u - 15 u
= 6 u

6 u = 36

1 u = 36 ÷ 6 = 6

Number of the fruits in the box altogether
= 20 u + 15 u + 21 u
= 56 u
= 56 x 6
= 336

Answer(s): 336
