A fruit-seller sold
45 of his grapefruits in the morning and
37 of his remaining grapefruits in the afternoon. If he had 40 grapefruits at the end of the day, find the total number of grapefruits he had at first.

|
| 28 u |
3 u |
4 u |
35 u |
Fraction of the grapefruits not sold in the morning
= 1 - 45
= 15
Number of grapefruits left = 4 u
4 u = 40
1 u = 40 ÷ 4 = 10
Total number of grapefruits
= 35 u
= 35 x 10
= 350
Answer(s): 350
