Fiona bought some fruits. She spent $10 more than
23 of her money on some mangoes. She then spent $5 more than 30% of the remaining money on some kiwis. Given that she had $16 left,
- How much did Fiona have at first?
- How many kilograms of kiwis did she buy if they cost $2 per kg?
(a)
100% - 30% = 70%
70% of remaining money
= 16 + 5
= 21
1% of remaining money
= 21 ÷ 70
= 0.3
100% of remaining money
= 100 x 0.3
= 30
13 of total money
= 30 + 10
= $40
33 of total money
= 3 x 40
= $120
Amount that Fiona had at first = $120
(b)
30% of the remaining money
= 30 x 30%
= 30 x
30100 = $9
Amount spent on kiwis
= 5 + 9
= $14
Weight of kiwis bought
= 14 ÷ 2
= 7 kg
Answer(s): (a) $120; (b) 5 kg
