A. Rs. 20000
B. Rs. 25000
C. Rs. 30000
D. Rs. 15000
Answer: Option B
Solution(By Examveda Team)
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
$$\eqalign{ & \therefore {\text{Monthly salary}} \cr & {\text{ = }}\frac{{300000}}{{12}} \cr & = {\text{Rs}}.\,25000 \cr} $$
