Lucy bought some fruits. She spent $16 more than
56 of her money on some peaches. She then spent $7 more than 10% of the remaining money on some mangoes. Given that she had $20 left,
- How much did Lucy have at first?
- How many kilograms of mangoes did she buy if they cost $5 per kg?
(a)
100% - 10% = 90%
90% of remaining money
= 20 + 7
= 27
1% of remaining money
= 27 ÷ 90
= 0.3
100% of remaining money
= 100 x 0.3
= 30
16 of total money
= 30 + 16
= $46
66 of total money
= 6 x 46
= $276
Amount that Lucy had at first = $276
(b)
10% of the remaining money
= 30 x 10%
= 30 x
10100 = $3
Amount spent on mangoes
= 7 + 3
= $10
Weight of mangoes bought
= 10 ÷ 5
= 2 kg
Answer(s): (a) $276; (b) 7 kg
