**Solution:**

Option(**C**) is correct

C.P of a unit quantity of 1st kind = Rs. 3.20

C.P of a unit quantity of 2nd kind = Rs. 2.90

Mean price = Rs.3.08

C.P of unit quantity C.P of unit quantity

of 1st kind of 2nd kind

(Rs. 3.20) (Rs. 2.90)

\ /

Mean Price

(Rs.3.08)

/ \

(3.08 – 2.90) : (3.20 – 3.08)

0.18 0.12

Required ratio = 0.18 : 0.12 =** 3 : 2**

I think the ratio is 2:3 because we make dearer-mean:mean-cheaper. Can somebody correct me if I am wrong

Ratio will be 3:2 only,since,

$\text{dearer-mean}:\text{mean-cheaper} :: \text{dearer} : \text{cheaper}$

$\Rightarrow \text{dearer} : \text{cheaper}:: 0.18 : 0.12$

$\Rightarrow \text{dearer} : \text{cheaper}:: 3 : 2$
