Question
Ram and Lakhan started a business by investing Rs.
72000 and Rs. 90000 respectively. After 4 months Lakhan withdraws 4/9 of his investment. In 5 months after, he again invested 11/9 of its original investment. If the total earned profit at the end of the year, is Rs. 234480, then who will get more money and by how much?Solution
Total Capital invested by Ram in 1 year = 72000 × 12 = Rs. 864000  Total Capital invested by Lakhan in 1 year = 90000 × 4 + (90000 - 40000) × 5 + (50000 + 110000) × 3 = 360000 + 250000 + 480000 = 1090000 
According to the question, (432 + 545) units = 234480 977 units = 234480 1 unit = Rs. 240 Difference in Profit = (545 - 432) × 240 = Rs . 27120 It means Lakhan will get Rs. 27120 more than Ram.Â
