Jean bought some fruits. She spent $11 more than
34 of her money on some grapefruits. She then spent $7 more than 20% of the remaining money on some kiwis. Given that she had $25 left,
- How much did Jean have at first?
- How many kilograms of kiwis did she buy if they cost $3 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 25 + 7
= 32
1% of remaining money
= 32 ÷ 80
= 0.4
100% of remaining money
= 100 x 0.4
= 40
14 of total money
= 40 + 11
= $51
44 of total money
= 4 x 51
= $204
Amount that Jean had at first = $204
(b)
20% of the remaining money
= 40 x 20%
= 40 x
20100 = $8
Amount spent on kiwis
= 7 + 8
= $15
Weight of kiwis bought
= 15 ÷ 3
= 5 kg
Answer(s): (a) $204; (b) 7 kg
