Risa bought some fruits. She spent $11 more than
45 of her money on some pomegranates. She then spent $9 more than 30% of the remaining money on some mangoes. Given that she had $26 left,
- How much did Risa have at first?
- How many kilograms of mangoes did she buy if they cost $4 per kg?
(a)
100% - 30% = 70%
70% of remaining money
= 26 + 9
= 35
1% of remaining money
= 35 ÷ 70
= 0.5
100% of remaining money
= 100 x 0.5
= 50
15 of total money
= 50 + 11
= $61
55 of total money
= 5 x 61
= $305
Amount that Risa had at first = $305
(b)
30% of the remaining money
= 50 x 30%
= 50 x
30100 = $15
Amount spent on mangoes
= 9 + 15
= $24
Weight of mangoes bought
= 24 ÷ 4
= 6 kg
Answer(s): (a) $305; (b) 9 kg
