Word Problem 1
Problem 1: In what proportion must a man mix milk at Rs 11 per liter with milk at Rs 6 per liter, so that the mixture may be worth Rs 8 per liter?
a) 2:3 b) 3:2 c) 5:7 d) 5:6
Solution:
Let milk type 1=M1 = Rs 11 per liter
Let milk type 2 =M2= Rs 6 per liter
Let proportion quantities for desired mixture weight / liter wise be;
‘y ‘ for milk type M1
‘z’ for milk type M2
Now we arrange data as under;
Now mixture price should be equale to the sum of prices of both types of milks separately;
Mixture price = Price of M1 + Price of M2
So, both types to be mixed in 2:3 ratio
