**Q. Two kinds of rice, 1st costs Rs.13 per kg and 2nd costs Rs.19 per kg are mixed together. Find the ratio in which the 2 types are mixed so that the mixture costs Rs.14.2 per kg?***- Published on 06 Jul 15***a.** 3:1

**b.** 4:1

**c.** 3:4

**d.** 4:3

**ANSWER: 4:1**

Let the total quantity of mixture be 1. If quantity of 1st type is x then quantity of the 2nd type will be (1-x)

Therefore, 13x + 19(1-x) = 14.2

13x -19x + 19 = 14.2

4.8 = 6x

x = 0.8 ; (1-x) = 0.2

Therefore, the ratio is 0.8 : 0.2 = 4:1
