The number of kiwis Japheth bought in May was 40% more than in April. In June, he bought 70% less kiwis than in May. If there were 174 less kiwis in June than April, how many kiwis did Japheth buy in May?

70 u |

100% + 40 = 140%
140% =
140100 =
75May : April = 7 : 5
100% - 70% = 30%
30% =
30100 =
310 June : May = 3 : 10
The number of kiwis in May is repeated. Make the number of kiwis in May is the same. LCM of 7 and 10 is 70.
Number of less kiwis in June than April
= 50 u - 21 u
= 29 u
29 u = 174
1 u = 174 ÷ 29 = 6
Number of kiwis that Japheth bought in May
= 70 u
= 70 x 6
= 420
Answer(s): 420
