Usha bought some fruits. She spent $11 more than
56 of her money on some pomegranates. She then spent $4 more than 20% of the remaining money on some mangoes. Given that she had $20 left,
- How much did Usha have at first?
- How many kilograms of mangoes did she buy if they cost $5 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 20 + 4
= 24
1% of remaining money
= 24 ÷ 80
= 0.3
100% of remaining money
= 100 x 0.3
= 30
16 of total money
= 30 + 11
= $41
66 of total money
= 6 x 41
= $246
Amount that Usha had at first = $246
(b)
20% of the remaining money
= 30 x 20%
= 30 x
20100 = $6
Amount spent on mangoes
= 4 + 6
= $10
Weight of mangoes bought
= 10 ÷ 5
= 2 kg
Answer(s): (a) $246; (b) 4 kg
