SSC CGL Tier II 12 Jan 2017 Paper 1

(3) Let A‘s income be Rs. 2x.
∴ B’s income = Rs. (2x – 140)
C’s income = Rs. 3x
∴ D’s income = Rs. (3x – 80)
According to the question,
B : D = 1 : 2
∴ 2 (2x – 140) = 3x – 80
⇒ 4x – 280 = 3x – 80
⇒ 4x – 3x = 280 – 80
⇒ x = Rs. 200
∴ A’s income = Rs. (2 × 200) = Rs. 400
B’s income = Rs. (400 – 140) = Rs. 260
C’s income = Rs. (3 × 200) = Rs. 600
D’s income = Rs. (600 – 80) = Rs. 520
