Anna bought some fruits. She spent $13 more than
23 of her money on some lemons. She then spent $4 more than 20% of the remaining money on some persimmons. Given that she had $20 left,
- How much did Anna have at first?
- How many kilograms of persimmons did she buy if they cost $2 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
13 of total money
= 30 + 13
= $43
33 of total money
= 3 x 43
= $129
Amount that Anna had at first = $129
(b)
20% of the remaining money
= 30 x 20%
= 30 x
20100 = $6
Amount spent on persimmons
= 4 + 6
= $10
Weight of persimmons bought
= 10 ÷ 2
= 5 kg
Answer(s): (a) $129; (b) 4 kg
