Shiyun bought some fruits. She spent $13 more than
56 of her money on some kiwis. She then spent $7 more than 10% of the remaining money on some passion fruits. Given that she had $20 left,
- How much did Shiyun have at first?
- How many kilograms of passion fruits did she buy if they cost $5 per kg?
(a)
100% - 10% = 90%
90% of remaining money
= 20 + 7
= 27
1% of remaining money
= 27 ÷ 90
= 0.3
100% of remaining money
= 100 x 0.3
= 30
16 of total money
= 30 + 13
= $43
66 of total money
= 6 x 43
= $258
Amount that Shiyun had at first = $258
(b)
10% of the remaining money
= 30 x 10%
= 30 x
10100 = $3
Amount spent on passion fruits
= 7 + 3
= $10
Weight of passion fruits bought
= 10 ÷ 5
= 2 kg
Answer(s): (a) $258; (b) 7 kg
