A box contains some passion fruits, chikoos and pears. 0.8 of the passion fruits is equal to 70% of the chikoos. The number of pears is ⁴₇ of the total number of chikoos and passion fruits. If there are 8 more pears than chikoos, how many fruits are there in the box altogether?

Passion Fruits	Chikoos	Pears
7x7	8x7
7x15		4x15
49 u	56 u	60 u

0.8 = ⁸₁₀= ⁴₅
70% = ⁷⁰₁₀₀ = ⁷₁₀

0.8 of the passion fruits is equal to 70% of the chikoos. Make the numerators the same.  LCM of 4 and 7 is 28.

4x75x7 of the passion fruits = 7x410x4 of the chikoos
2835 of the passion fruits = 2840 of the chikoos 

Passion Fruits : Chikoos
35 : 40 _(÷5)
7 : 8

The total number of passion fruits and chikoos is repeated.  Make the total number of passion fruits and chikoos the same.  LCM of 15 and 7 is 105.

Number of more pears than chikoos
= 60 u - 56 u
= 4 u

4 u = 8

1 u = 8 ÷ 4 = 2

Number of the fruits in the box altogether
= 49 u + 56 u + 60 u
= 165 u
= 165 x 2
= 330

Answer(s): 330
