(a)
4 ÷ 2 x 5 = 10
4 ÷ 2 x 3 = 6
Total mass of venison and mutton bought
= 6 u + 5 u + 10
= 11 u + 10
11 u + 10 = 98
11 u = 98 - 10
11 u = 88
1 u = 88 ÷ 11 = 8
Mass of mutton bought
= 5 u + 10
= 5 x 8 + 10
= 40 + 10
= 50 kg
(b)
Mass of venison bought
= 6 u
= 6 x 8
= 48 kg
Answer(s): (a) 50 kg; (b) 48 kg
