Ratio of rent = 6 : 10 : 12 = 3 : 5 : 6
∴ Pandeyji has to pay = Rs. 350 x (6/14)

Correct Option: D

Ratio of rent = 6 : 10 : 12 = 3 : 5 : 6
∴ Pandeyji has to pay = Rs. 350 x (6/14) = Rs. 150

For management A receive = Rs. 960
Balance Amount = Rs. (9600 - 960) = Rs. 86400
Ratio of their investment = 12000 : 20000 = 3 : 5

Correct Option: B

For management A receive = Rs. 960
Balance Amount = Rs. (9600 - 960) = Rs. 86400
Ratio of their investment = 12000 : 20000 = 3 : 5
∴ A's share = Rs. 8640 x (3/8) = Rs. 3240
So, A receive = Rs. (3240 + 960) = Rs. 4200

Sanjay's investment for 1 months = 15000 x 12 = Rs. 180000
Komal's investment for 1 months = 15000 x 8 + (15000 - 10000) x 4
= 120000 + 20000
= Rs. 140000

Correct Option: A

Sanjay's investment for 1 months = 15000 x 12 = Rs. 180000
Komal's investment for 1 months = 15000 x 8 + (15000 - 10000) x 4
= 120000 + 20000
= Rs. 140000

∴ Ratio between the investment of Sanjay and Komal
= 180000 : 140000 = 9 : 7
∴ Sanjay's profit = [9/(9 + 7)] x 32000 = Rs. 18000

Let the total profit be Rs. 100
After paying to Charity,
A's share = Rs. 95 x (3/5) = Rs. 57
If A's share is Rs. 57, then total profit = Rs. 100

Correct Option: C

Let the total profit be Rs. 100
After paying to Charity,
A's share = Rs. 95 x (3/5) = Rs. 57
If A's share is Rs. 57, then total profit = Rs. 100
If A's share is Rs. 855, then total profit = Rs. 855 x (100/51) = Rs. 1500

∵ Ratio of shares = (9000 x 12) : (8000 x 7) = 108 : 56 = 27 : 14
∴ Sudhakar's share = Rs. 6970 x (14/41)

Correct Option: C

∵ Ratio of shares = (9000 x 12) : (8000 x 7) = 108 : 56 = 27 : 14
∴ Sudhakar's share = Rs. 6970 x (14/41) = Rs. 2380
