Question
Cost price of wheat (per kg) of type 'A' and 'B' is Rs. 84
and Rs. 132 respectively. Both types are mixed and sold at Rs. 156 per kg at a profit of 30%. Find the ratio in which wheat of type 'B' is mixed with wheat of type 'A'.Solution
Cost price of mixture = (156 / 1.3) = Rs. 120
Let 'm' kg and 'n' kg of wheat of type 'A' and 'B' respectively be mixed.
So, (84m + 132n) ÷ (m + n) = 120
Or, 84m + 132n = 120m + 120n
Or, 12n = 36m
Or, m:n = 3:1
