The incomes of A of B are in the ratio 3:2 and their expenditure are in the ratio 5:3 if each saves rupees 2000, what is their income?
a) 32000
b) 20000
c) 1190
d) 8000
e) None of these
Let the income be 3x and 2x. It is given that the saving of each is Rs. 2000.
Then, their expenditures are 3x – 2000 and 2x – 2000
Again, (3x – 2000)/(2x – 2000) = 5/3
=> 3(3x – 2000) = 5(2x – 2000)
=> 9x – 6000 = 10x – 10000
=> 9x -10x = -10000+ 6000
=> -x = -4000
=> x = 4000
Therefore, their salaries are 3 x 4000 = 12000 and 2 x 4000 = 8000
Answer: d)
