A fruit seller sells only kiwis and chikoos. The ratio of kiwis to chikoos is 2 : 5. A total of 110 fruits are added. The number of kiwis becomes 4 times as many as before and the number of chikoos becomes 2 times as many as before. How many fruits are there in the end?

	Comparing kiwis at first and in the end	Kiwis	Chikoos	Comparing chikoos at first and in the end
Before	1x2 = 2 u	2 u	5 u	1x5 = 5 u
Change		+ 110
After	4x2 = 8 u	8 u	10 u	2x5 = 10 u

The number of chikoos at first is repeated.  Make the number of chikoos at first the same.  LCM of 1 and 5 is 5.

The number of kiwis at first is repeated. Make the number of kiwis at first the same. LCM of 1 and 2 is 2.

Number of fruits at first
= 2 u + 5 u
= 7 u

Number of fruits in the end
= 8 u + 10 u
= 18 u

Number of fruits added
= 18 u - 7 u 
= 11 u

11 u = 110

1 u = 110 ÷ 11 = 10

Number of fruits in the end
= 18 u
= 18 x 10
= 180

Answer(s): 180
