A's income is Rs. 140 more than B's income and C's income is Rs. 80 more than D's. If the ratio of A's and C's income is 2 : 3 and the ratio of B's and D's income is 1: 2, then the incomes of A, B, C, and D are respectively.

A) Rs. 60, Rs.120, Rs. 320 and Rs. 240

B) Rs.300, Rs.160, Rs. 600 and Rs. 520

C) Rs.400, Rs.260, Rs. 600 and Rs. 520

D) Rs.320, Rs.180, Rs. 480 and Rs. 360

Let A: C= 2x:3x

B: D = y: 2y

A's income is Rs. 140 more than B's income

It means 2x-y=140 …………. i

C's income is Rs. 80 more than D's.

It means 3x-2y= 80………ii

Solve equation I and II

x = 200, y= 260

A= 2x= 400

B= y= 260

C= 3x= 600

D=2y = 520

Answer = C
