A and B invests Rs.3000 and Rs.4000 respectively in a business. If A doubles his capital after 6 months. In what ratio should A and B divide that year's profit?

Correct answer: B. 9:8

  • A. 9:10
  • B. 9:8
  • C. 3:4
  • D. 39:49Islamic Studies Quiz

Explanation

Profit is divided according to capital multiplied by time. A's investment units are Rs.3000 x 6 months + Rs.6000 x 6 months = Rs.54000-months, while B's are Rs.4000 x 12 months = Rs.48000-months, giving 54000:48000 = 9:8. The likely mistake is option c, 3:4, which compares only the original capitals and ignores A's increase after 6 months.
