Jane bought some fruits. She spent $17 more than
23 of her money on some persimmons. She then spent $5 more than 20% of the remaining money on some dragonfruits. Given that she had $23 left,
- How much did Jane have at first?
- How many kilograms of dragonfruits did she buy if they cost $2 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 23 + 5
= 28
1% of remaining money
= 28 ÷ 80
= 0.35
100% of remaining money
= 100 x 0.35
= 35
13 of total money
= 35 + 17
= $52
33 of total money
= 3 x 52
= $156
Amount that Jane had at first = $156
(b)
20% of the remaining money
= 35 x 20%
= 35 x
20100 = $7
Amount spent on dragonfruits
= 5 + 7
= $12
Weight of dragonfruits bought
= 12 ÷ 2
= 6 kg
Answer(s): (a) $156; (b) 5 kg
