At a mart, the ratio of guavas to peaches was 5 : 11. After Risa bought two-fifths of the peaches, there was a total of 638 guavas and peaches left at the mart. How many fruits were there at first?

The number of peaches at first is repeated. Make the number of peaches at first the same. LCM of 11 and 5 is 55.
Total number of fruits left
= 25 u + 33 u
= 58 u
58 u = 638
1 u = 638 ÷ 58 = 11
Number of fruits at first
= 25 u + 55 u
= 80 u
= 80 x 11
= 880
Answer(s): 880
