3 u + 14 |
10 u |
Fraction of curry powder left after using
14 of it
= 1 -
14 =
34 Amount of curry powder left after using some = 3 u
Amount of curry powder after buying 14 kg of curry powder = 3 u + 14
3 u + 14 = 10 u
10 u - 3 u = 14
7 u = 14
1 u = 14 ÷ 7 = 2
Amount of curry powder that Mrs Chium had at first
= 4 u
= 4 x 2
= 8 kg
Answer(s): 8 kg
