Mr Vincent sold some pears, apples and lemons. The ratio of the number of pears sold to the total number of fruits sold was 3 : 10. The ratio of the number of apples sold to the number of lemons sold was 1 : 20. He sold 22 more lemons than pears. Find the total number of fruits that he sold.

The total number of apples and lemons is repeated. Make the total number of apples and lemons the same. LCM of 7 and 21 is 21.
Number of more lemons than pears
= 20 u - 9 u
= 11 u
11 u = 22
1 u = 22 ÷ 11 = 2
Total number of fruits that Mr Vincent sold
= 30 u
= 30 x 2
= 60
Answer(s): 60
