Yen had some fruits at her stall.
13 of them were plums,
14 of the remainder were dates and the rest were pears. The amounts earned for each plum, each date and each pear sold are $1.90, $1.40 and $1.70 respectively. The number of plums sold to the number of dates sold to the number of pears sold was 5 : 3 : 3. In total, she sold
13 of the fruits and earned $263.20. How many pears did she have at first?

Total amount that Yen earned
= 9.5 u + 4.2 u + 5.1 u
= 18.8 u
18.8 u = 263.20
1 u = 263.20 ÷ 18.8 = 14
Total number of fruits sold
= 5 u + 3 u + 3 u
= 11 u
= 11 x 14
= 154
Total number of fruits at first
= 154 ÷
13= 154 x 3
= 462
Total number of fruits at first
= 2 p + 1 p + 3 p
= 6 p
6 p = 462
1 p = 462 ÷ 6 = 77
Number of pears that Yen had at first
= 3 p
= 3 x 77
= 231
Answer(s): 231
