Gillian bought some fruits. She spent $14 more than
23 of her money on some pears. She then spent $5 more than 30% of the remaining money on some lemons. Given that she had $16 left,
- How much did Gillian have at first?
- How many kilograms of lemons 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 + 14
= $44
33 of total money
= 3 x 44
= $132
Amount that Gillian had at first = $132
(b)
30% of the remaining money
= 30 x 30%
= 30 x
30100 = $9
Amount spent on lemons
= 5 + 9
= $14
Weight of lemons bought
= 14 ÷ 2
= 7 kg
Answer(s): (a) $132; (b) 5 kg
