Jade bought some fruits. She spent $15 more than
23 of her money on some persimmons. She then spent $5 more than 10% of the remaining money on some dragonfruits. Given that she had $22 left,
- How much did Jade have at first?
- How many kilograms of dragonfruits did she buy if they cost $2 per kg?
(a)
100% - 10% = 90%
90% of remaining money
= 22 + 5
= 27
1% of remaining money
= 27 ÷ 90
= 0.3
100% of remaining money
= 100 x 0.3
= 30
13 of total money
= 30 + 15
= $45
33 of total money
= 3 x 45
= $135
Amount that Jade had at first = $135
(b)
10% of the remaining money
= 30 x 10%
= 30 x
10100 = $3
Amount spent on dragonfruits
= 5 + 3
= $8
Weight of dragonfruits bought
= 8 ÷ 2
= 4 kg
Answer(s): (a) $135; (b) 5 kg
