The total mass of 3 packets of peppercorn and 2 bags of sesame seed was 34 kg. Each bag of sesame seed was 8 kg lighter than each packet of peppercorn.
- What was the mass of 1 packet of peppercorn?
- What was the mass of 1 bag of sesame seed?
(a)
Mass of a bag of sesame seed = 1 u
Mass of a packet of peppercorn = 1 u + 8
3 x (1 u + 8) + 2 x 1 u = 34
3 u + 24 + 2 u = 34
3 u + 2 u = 34 - 24
5 u = 10
1 u = 10 ÷ 5 = 2
Mass of 1 packet of peppercorn
= 2 + 8
= 10 kg
(b)
Mass of 1 bag of sesame seed = 1 u = 2 kg
Answer(s): (a) 10 kg; (b) 2 kg
