A invested Rs. 40000 for 4 months and Rs. (40000 – 15000) = Rs. 25000 for (12 – 4) = 8 months
Similarly, B invested Rs. 10000 for 4 months and Rs. (10000 + 15000) = Rs. 25000 for (12 – 4) = 8 months
Hence,
Share of their profits
⇒ (40000 × 4 + 25000 × 8) ∶ (10000 × 4 + 25000 × 8)
⇒360000 ∶ 240000
⇒ 3 ∶ 2
