Xandra bought some fruits. She spent $20 more than
34 of her money on some chikoos. She then spent $6 more than 10% of the remaining money on some persimmons. Given that she had $21 left,
- How much did Xandra have at first?
- How many kilograms of persimmons did she buy if they cost $3 per kg?
(a)
100% - 10% = 90%
90% of remaining money
= 21 + 6
= 27
1% of remaining money
= 27 ÷ 90
= 0.3
100% of remaining money
= 100 x 0.3
= 30
14 of total money
= 30 + 20
= $50
44 of total money
= 4 x 50
= $200
Amount that Xandra had at first = $200
(b)
10% of the remaining money
= 30 x 10%
= 30 x
10100 = $3
Amount spent on persimmons
= 6 + 3
= $9
Weight of persimmons bought
= 9 ÷ 3
= 3 kg
Answer(s): (a) $200; (b) 6 kg
