If 60% of A = 1.2 of B = $$\frac{2}{5}$$ of C, then find A : B : C.

Correct option is D

Given:

60% of A = 1.2 of B=$$\frac{2}{5}$$​ of C

Solution:

60% of A = 1.2 of B

​$$\frac{60}{100}$$​ of A = 1.2 of B

6A = 12B

​$$\frac{A}{B} = \frac{2}{1}$$​​

A:B = 2:1

1.2B$$=\frac{2}{5}$$​ of C

$$\frac{B}{C} = \frac{2}{5 \times 1.2}$$​​

B:C = 2:6

Equating B in the ratio

A:B =$$(2:1) \times 2$$​ = 4:2

Then A:B:C = 4 : 2 : 6 = 2 : 1 : 3
