Answer 2

Answer:

10 quintals

Step-by-step explanation:

C.P of mixtures = 195 * 100/130 = 150  

First grain rate is 100 rs/quintal

2nd grain rate is 160 rs/quintal

So,

100 --------------- 160

           150

10                        50

Ratio = 1:5

x/50 = 1/5

5x = 50

x = 10

So, answer is 10 quintals
