The number of coconuts Tommy bought in September was 10% more than in August. In October, he bought 60% less coconuts than in September. If there were 168 more coconuts in August than October, how many coconuts did Tommy buy in August?

100% + 10 = 110%

1110September : August = 11 : 10
100% - 60% = 40%
40% =
40100 =
25 October : September = 2 : 5
The number of coconuts in September is repeated. Make the number of coconuts in September is the same. LCM of 11 and 5 is 55.
Number of more coconuts in August than October
= 50 u - 22 u
= 28 u
28 u = 168
1 u = 168 ÷ 28 = 6
Number of coconuts that Tommy bought in August
= 50 u
= 50 x 6
= 300
Answer(s): 300
