Gillian bought some fruits. She spent $17 more than
23 of her money on some pears. She then spent $7 more than 10% of the remaining money on some guavas. Given that she had $20 left,
- How much did Gillian have at first?
- How many kilograms of guavas did she buy if they cost $2 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
13 of total money
= 30 + 17
= $47
33 of total money
= 3 x 47
= $141
Amount that Gillian had at first = $141
(b)
10% of the remaining money
= 30 x 10%
= 30 x
10100 = $3
Amount spent on guavas
= 7 + 3
= $10
Weight of guavas bought
= 10 ÷ 2
= 5 kg
Answer(s): (a) $141; (b) 7 kg
