will he have left?
1. His profit share and his debt match exactly
2. Rs.200 3. Rs.400
4. Rs.350​

Answer 1

Step-by-step explanation:

Interest = (PRT)/100

P=Principle

R = Rate

T = Time

Assuming the Rate (R) is the same

Interest earned by A = (50000 x R x 6/12)/100 = 250R

Interest earned by B = (60000 x R x 4/12)/100 = 200R

Interest earned by C = (80000 x R x 5/12)/100 = 333 1/3 R

They will share the earnings in the ratio = 250R : 200R : 333 1/3 R

                                                                = 250 : 200 : 333 1/3

Total ratio = 250 + 200 + 333 1/3 = 783 1/3

A gets = 250/ 783 1/3  x 18800 = Rs. 6000

B gets = 200/ 783 1/3 x 18800 = Rs. 4800

C gets = 333 1/3 /783 1/3 x 18800 = 8000
