Ratio between the investment of Pramod and Vikas = 40000 x 12 : 60000 x 8
= 480000 : 480000 = 1 : 1Correct Option: A
Ratio between the investment of Pramod and Vikas = 40000 x 12 : 60000 x 8
= 480000 : 480000 = 1 : 1
Total profit = Rs. 16000
share of Vikas in profit = 16000/2 = Rs. 8,000

Suppose B invested the money for N months.
Then the ratio of investment = (12 x 11 : 11 x N) = 12 : N
∴ 12/N = 4/1Correct Option: A
Suppose B invested the money for N months.
Then the ratio of investment = (12 x 11 : 11 x N) = 12 : N
∴ 12/N = 4/1
⇒ N = 3 months.

Suppose B invested Rs. x for y months.
Then A's investment is Rs. 3x for 2y months.
Ratio of investment of A and B = 6xy : xy = 6 : 1.Correct Option: C
Suppose B invested Rs. x for y months.
Then A's investment is Rs. 3x for 2y months.
Ratio of investment of A and B = 6xy : xy = 6 : 1.
Now B's share = Rs. 4,000
∴ A's share = Rs. 24, 000
Hence, Total profit = Rs. 28,000

Ratio of shares = 27000 : 81000 : 72000 = 3 : 9 : 8
If Ram's share is Rs. 9 then total profit = Rs. 20Correct Option: C
Ratio of shares = 27000 : 81000 : 72000 = 3 : 9 : 8
If Ram's share is Rs. 9 then total profit = Rs. 20
If Ram's share is Rs. 36000 then total profit = Rs. (20/9) x 36000
= Rs. 80000

Let C's share = Rs. N
Then B's share = Rs. N/2
and A's share = Rs. N/4
∴ A : B : C = N/4 : N/2 : N = 1 : 2 : 4Correct Option: C
Let C's share = Rs. N
Then B's share = Rs. N/2
and A's share = Rs. N/4
∴ A : B : C = N/4 : N/2 : N = 1 : 2 : 4
Hence C's share = Rs. 700 x (4/7) = Rs. 400
