Zara bought some fruits. She spent $11 more than
45 of her money on some dragonfruits. She then spent $4 more than 20% of the remaining money on some lemons. Given that she had $28 left,
- How much did Zara have at first?
- How many kilograms of lemons did she buy if they cost $4 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 28 + 4
= 32
1% of remaining money
= 32 ÷ 80
= 0.4
100% of remaining money
= 100 x 0.4
= 40
15 of total money
= 40 + 11
= $51
55 of total money
= 5 x 51
= $255
Amount that Zara had at first = $255
(b)
20% of the remaining money
= 40 x 20%
= 40 x
20100 = $8
Amount spent on lemons
= 4 + 8
= $12
Weight of lemons bought
= 12 ÷ 4
= 3 kg
Answer(s): (a) $255; (b) 4 kg
