Irene bought some fruits. She spent $10 more than
23 of her money on some mangoes. She then spent $8 more than 20% of the remaining money on some mangosteens. Given that she had $16 left,
- How much did Irene have at first?
- How many kilograms of mangosteens did she buy if they cost $2 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 16 + 8
= 24
1% of remaining money
= 24 ÷ 80
= 0.3
100% of remaining money
= 100 x 0.3
= 30
13 of total money
= 30 + 10
= $40
33 of total money
= 3 x 40
= $120
Amount that Irene had at first = $120
(b)
20% of the remaining money
= 30 x 20%
= 30 x
20100 = $6
Amount spent on mangosteens
= 8 + 6
= $14
Weight of mangosteens bought
= 14 ÷ 2
= 7 kg
Answer(s): (a) $120; (b) 8 kg
