Question
‘Farhan’ started a business by investing Rs. 1,000.
After 8 months, ‘Gautam’ joined him with 120% of Farhan’s investment. If the total profit after a year is Rs. 6,300, what is Gautam’s share?Solution
Investment by Gautam = 1000 × 1.2 = Rs. 1,200
Ratio = (12 × 1000):(4 × 1200) = 12000:4800 = 5:2
Gautam’s share = 6300 × (2/7) = Rs. 1,800
