Mr Billy sold some kiwis, lemons and apples. The ratio of the number of kiwis sold to the total number of fruits sold was 2 : 7. The ratio of the number of lemons sold to the number of apples sold was 6 : 19. He sold 18 more apples than kiwis. Find the total number of fruits that he sold.

The total number of lemons and apples is repeated. Make the total number of lemons and apples the same. LCM of 5 and 25 is 25.
Number of more apples than kiwis
= 19 u - 10 u
= 9 u
9 u = 18
1 u = 18 ÷ 9 = 2
Total number of fruits that Mr Billy sold
= 35 u
= 35 x 2
= 70
Answer(s): 70
