Question
Cost price of wheat (per kg) of type 'A' and 'B' is Rs.
78 and Rs. 102 respectively. Both types are mixed and sold at Rs. 108 per kg at a profit of 20%. Find the ratio in which wheat of type 'B' is mixed with wheat of type 'A'.Solution
Cost price of mixture = (108 / 1.2) = Rs. 90
Let 'm' kg and 'n' kg of wheat of type 'A' and 'B' respectively be mixed.
So, (78m + 102n) ÷ (m + n) = 90
Or, 78m + 102n = 90m + 90n
Or, 12n = 12m
Or, m:n = 1:1
