 ✖ A. 3 : 4 ✖ B. 2 : 3 ✔ C. 3 : 2 ✖ D. 4 : 3

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

Because according to me 2:3 is right.

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,

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

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

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