Marion bought some fruits. She spent $12 more than
45 of her money on some guavas. She then spent $5 more than 10% of the remaining money on some kiwis. Given that she had $22 left,
- How much did Marion have at first?
- How many kilograms of kiwis did she buy if they cost $4 per kg?
(a)
100% - 10% = 90%
90% of remaining money
= 22 + 5
= 27
1% of remaining money
= 27 ÷ 90
= 0.3
100% of remaining money
= 100 x 0.3
= 30
15 of total money
= 30 + 12
= $42
55 of total money
= 5 x 42
= $210
Amount that Marion had at first = $210
(b)
10% of the remaining money
= 30 x 10%
= 30 x
10100 = $3
Amount spent on kiwis
= 5 + 3
= $8
Weight of kiwis bought
= 8 ÷ 4
= 2 kg
Answer(s): (a) $210; (b) 5 kg
