  • Question
  • In a business, A invested 1200 rs. more than B. B invested his amount for 15 months while A invested for 4 months more than that of B. If total profit was 1240 rs. in which the profit of B is 280 Rs. less than that if A. then what was the invested amount of A?


  • Options
  • A. 6000
  • B. 7000
  • C. 5000
  • D. 8000

  • Correct Answer
  • 6000 

    Explanation

    Ans. 
    Let B?s investment = x rs.
    ? A?s investment =( x + 1200) rs.
    Ratio of the profits of A and B = (x+1200)*(15+4):x*15 = {19(x+1200)}:15x
    Now,let the total profit of A =y
    ? total profit of B = (y-280)
    But total profit = 1240
    ?y+(y-280)=1240
    ?2y=1520
    ?y= 760
    ?profit of A = 760rs.
    Profit of B = 760-280=480 rs.
    Ratio of profits= 760:480 = 19:12
    According to the question,

    19(x+1200)/15x = 19/12

    12x+14400 = 15x

    ?3x = 14400
    ?x = 4800 rs.
    ?investment of A = 4800+1200
                              = 6000 rs.
