If the annual income of A, B and C are in the ratio 1 : 3 : 7 and the total annual income of A and C is Rs. 800000, then the monthly salary of B (in Rs. ) is = ?
If the annual income of A, B and C are in the ratio 1 : 3 : 7 and the total annual income of A and C is Rs. 800000, then the monthly salary of B (in Rs. ) is = ? Correct Answer Rs. 25000
| A | : | B | : | C | |
| Annual Income | 1 | : | 3 | : | 7 |
| Let | x | : | 3x | : | 7x |
Given A + C ⇒ x + 7x = 8x
⇒ 8x = 800000
⇒ x = 100000
⇒ Annual salary of B = 3x
⇒ 3 × 100000 = 300000
$$\eqalign{ & \therefore {\text{Monthly salary}} \cr & {\text{ = }}\frac{{300000}}{{12}} \cr & = {\text{Rs}}.\,25000 \cr} $$
