  • Question

  • The incomes of two persons A and B are in the ratio 3 : 4. If each saves Rs.100 per month, the ratio of their expenditures is Rs. 1 : 2. Find their incomes.


  • Options
  • A. Rs. 100 and Rs.150
  • B. Rs. 150 and Rs.200
  • C. Rs.200 and Rs.250
  • D. Rs.250 and Rs.300

  • Correct Answer
  • Rs. 150 and Rs.200 

    Explanation

    Let the incomes of A and B be 3P and 4P.

    If each saves Rs. 100 per month, then their expenditures = Income - savings = (3P - 100) and (4P - 100).

     

    The ratio of their expenditures is given as 1 : 2.

    Therefor, (3P - 100) : (4P - 100) = 1 : 2

    Solving, We get P = 50. Substitute this value of P in 3P and 4P.

    Thus, their incomes are : Rs.150 and Rs.200
