Answer 2

The earnings of D is Rs. 22050.

Step-by-step explanation:

Since we have given that

Total earnings = Rs. 52950

Ratio of A and B = 3:7

Ratio of B and C = 4:9

Ratio of D and C = 7:6

So, it becomes,

A   :    B   :   C   :   D

3   :    7

          4   :    9

                    6    :    7

----------------------------------------

72  :   168  :  378  :  441

24  :    56  :  126   :  147

So, the earnings of D would be

$\dfrac{147}{353}\times 52950\\\\=22050$

Hence, the earnings of D is Rs. 22050.
