Zoe bought some fruits. She spent $18 more than
34 of her money on some mangosteens. She then spent $6 more than 30% of the remaining money on some lemons. Given that she had $15 left,
- How much did Zoe have at first?
- How many kilograms of lemons did she buy if they cost $3 per kg?
(a)
100% - 30% = 70%
70% of remaining money
= 15 + 6
= 21
1% of remaining money
= 21 ÷ 70
= 0.3
100% of remaining money
= 100 x 0.3
= 30
14 of total money
= 30 + 18
= $48
44 of total money
= 4 x 48
= $192
Amount that Zoe had at first = $192
(b)
30% of the remaining money
= 30 x 30%
= 30 x
30100 = $9
Amount spent on lemons
= 6 + 9
= $15
Weight of lemons bought
= 15 ÷ 3
= 5 kg
Answer(s): (a) $192; (b) 6 kg
