Question
Cost price of wheat (per kg) of type 'A' and 'B' is Rs.
90 and Rs. 150 respectively. Both are mixed and sold at Rs. 180 per kg at a profit of 50%. Find the ratio in which wheat of type 'B' is mixed with wheat of type 'A'.Solution
Cost price of mixture = (180 / 1.5) = Rs. 120
Let 'm' kg and 'n' kg of wheat of type 'A' and 'B' respectively be mixed.
So, (90m + 150n) ÷ (m + n) = 120
Or, 90m + 150n = 120m + 120n
Or, 30n = 30m
Or, m:n = 1:1
