The number of guavas Sean bought in February was 30% more than in January. In March, he bought 60% less guavas than in February. If there were 240 more guavas in January than March, how many guavas did Sean buy in January?

100% - 60% = 40%
40% =
40100 =
25 March : February = 2 : 5
The number of guavas in February is repeated. Make the number of guavas in February is the same. LCM of 13 and 5 is 65.
Number of more guavas in January than March
= 50 u - 26 u
= 24 u
24 u = 240
1 u = 240 ÷ 24 = 10
Number of guavas that Sean bought in January
= 50 u
= 50 x 10
= 500
Answer(s): 500
