In an examination, the marks obtained by Shantanu is 40% less than the marks obtained by Kamal, then marks obtained by Kamal is how much per cent more than the marks obtained by Shantanu?

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
= 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
= [(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
= [(25/2) x 15000] /100
= ? 1875

Number of employees leaving job
= 25% of 724 = (1/4) x 724 = 181

? Number of rest of the employees
= 724 - 181 = 543

Net effect = [- 12 - 4 + {(-12) (-4)/100}]%
= (-16 + 0.48)%
= -15.52%

Given that, a = 20% and b = 5%

According to the formula
Required percentage = [20 - 5 - {20 x (5/100)}% = 14%

Let original price be ? 100
Then, increased price = ? 125

? Reduction in consumption
= [(125 - 100)/125 ] x 100%
= (25/125) x 100 %
= 20%

Let original price be ? 100
Then, reduced price = ? 94
? Increase in consumption
= [(100 - 94)/94] x 100 %
= (6/94) x 100 %
= 6¹⁸/₄₇%

Let maximum marks be N.

According to the question,
40N/100 = 40 + 40
? 40N/100 = 80
? N = 200
