Let kamal's marks be 100
∴ Shantanu's marks = 60
Kamal has 40 marks more than Shantanu
∴ Required percentage = (40/60) x 100%

Correct Option: D

Let kamal's marks be 100
∴ Shantanu's marks = 60
Kamal has 40 marks more than Shantanu
∴ Required percentage = (40/60) x 100%
= 66²/₃ %

Ans = 12 x (26/100) x (5/78) x (38/100) x (7/152) x 10000

Correct Option: B

Ans = 12 x (26/100) x (5/78) x (38/100) x (7/152) x 10000
= 12 x (5/3) x (7/4)
= 35

Let a man have = ₹ N.
Remainder money, after losses 20% of his money
= N - 20% of N

Remainder money, after spending 25% of his remainder money
= 4N/5 - 25% of (4N/5)

Correct Option: C

Let a man have = ₹ N.
Remainder money, after losses 20% of his money
= N - 20% of N
= N - (N x 20)/100
= (5N - N)/5
= 4N/5

Remainder money, after spending 25% of his remainder money
= 4N/5 - 25% of (4N/5)
= 4N/5 - (4N/5) x (25/100)
= 4N/5 - N/5
= (4N - N)/5
= 3N/5

According to the question,
3N/5 = 480
⇒ x = 480 x 5/3 = ₹ 800

Given that, P = ₹ 15000, and Q = 8

According to the formula,
Required new price = [(100 - Q)/100] x P

Correct Option: B

Given that, P = ₹ 15000, and Q = 8

According to the formula,
Required new price = [(100 - Q)/100] x P
= [(100 - 8)/100] x 15000
= (92/100) x 15000
= ₹ 13800

Agent receives commission of the rate = 12¹/₂%
Total value of goods sold = ₹ 15000
∴ Agent's commission = 12¹/₂% of 15000

Correct Option: A

Agent receives commission of the rate = 12¹/₂%
Total value of goods sold = ₹ 15000
∴ Agent's commission = 12¹/₂% of 15000
= [(25/2) x 15000] /100
= ₹ 1875
