The annual income of A and B are In the ratio 4 : 3 and the ratio of their expenditures is 3:2. If each of them saves Rs.600 in the year, the annual income of A is
1). Rs.4800
2). Rs.1800
3). Rs.1200
4). Rs.2400
Let the annual income of A and
B be 4x and 3x respectively. Also
let their annual expenditures be
rs 3y and 2y respectively
According to question,
4x – 3y = 600 ...(i)
3x – 2y = 600 ...(ii)
From equation (i) and (ii)
4x –3y = 3x – 2y
=> x = y
From equation (i)
4x – 3x = 600
x = 600
Annual income of A
= 4x = 4 × 600 = 2400
