Fiona bought some fruits. She spent $17 more than
23 of her money on some guavas. She then spent $4 more than 30% of the remaining money on some pears. Given that she had $24 left,
- How much did Fiona have at first?
- How many kilograms of pears did she buy if they cost $2 per kg?
(a)
100% - 30% = 70%
70% of remaining money
= 24 + 4
= 28
1% of remaining money
= 28 ÷ 70
= 0.4
100% of remaining money
= 100 x 0.4
= 40
13 of total money
= 40 + 17
= $57
33 of total money
= 3 x 57
= $171
Amount that Fiona had at first = $171
(b)
30% of the remaining money
= 40 x 30%
= 40 x
30100 = $12
Amount spent on pears
= 4 + 12
= $16
Weight of pears bought
= 16 ÷ 2
= 8 kg
Answer(s): (a) $171; (b) 4 kg
