Capital Ratio of Rohit and Simran
Ratio of profit = Ratio of Rohit’s capital × time : Ratio of Simran’s capital × time
⇒ 3 : 1 = 75000 × 12 : 60000 × t
⇒ 3 : 1 = 5 × 3 : t
⇒ 3/1 = 15/t
⇒ t = 5 months
∴ Simran joins Rohit after = 12 - 5 = 7 months
Ratio of profit = Ratio of Rohit’s capital × time : Ratio of Simran’s capital × time
⇒ 3 : 1 = 75000 × 12 : 60000 × t
⇒ 3 : 1 = 5 × 3 : t
⇒ 3/1 = 15/t
⇒ t = 5 months
∴ Simran joins Rohit after = 12 - 5 = 7 months
