A man’s basic pay for a 40 hour week is Rs. 20 overtime is paid for at 25 % above the basic rate, in a certain week he worked overtime and his total wage was Rs. 25. He therefore worked for a total of:________?

A. 45 hours
B. 47 hours
C. 48 hours
D. 50 hours
Explanation:
Basic rate per hour = Re. (20/40) = Re. 1/2.
Overtime per hour = 125 % of Re. 1/2 = Re.5/8.
He worked x hours overtime.
Then 20 + 5/8 x = 25 (or) = 5/8 x = 5
X = 40/5 = 8 hours
=> he worked in all for (40 + 8) = 48 hours.

On decreasing the price of T.V. sets by 30 % its sale is increased by 20 %. What is the effect on the revenue received by the shopkeeper?

A. 10 % increase
B. 10 % decrease
C. 16 % increase
D. 16 % decrease
Let price = Rs. 100, Sale = 100
Then Sale Value = Rs. (100 × 100) = Rs. 10000
New Sale Value = Rs. (70 × 120) = Rs. 8400
Decrease % = (1000/10000 x 100) % = 16 %

A. 11250
B. 15000
C. 26250
D. 37500
Explanation:
Let the votes polled by the winning candidate be x.
Then, (x – 15000) = 30 % of [x + (x – 15000)]
or x = 26250.

A student who secures 20 % marks in an examination fails by 30 marks. Another student who secures 32 % marks gets 42 marks more than those required to pass. The percentage of marks required to pass is:________?

A. 20%
B. 25 %
C. 28%
D. 30%
Explanation:
20 % of x + 30 = 32 % of x – 42
Or 12 % of x = 72.
So, x = (72 ×100)/12 = 600
Pass marks = 20 % of 600 + 30 = 150
Pass Percentage =[1/4 x 100]%= 25 %

5 % income of a is equal to 15 % income of B and 10 % income of B is equal to 20 % income of C if the income of c is Rs. 200, then total income of A, B and C is :_________?

A. Rs. 6000
B. Rs. 18000
C. Rs. 20000
D. Rs. 14000
Explanation:
5 % A = 15 % B and 10 % B = 20 % C.
A/20 = 3B/20 and B/10 = C/5
or B = 2C. A/20 = 3/20 × 2c = 3/10
C = 3/10 × 2000 = 600
A = (600 × 20) = 12000,
B = (2 × 2000) = 4000
A + B + C = (12000 + 4000 + 2000) = 18000
Therefore, Rs. 18000/-
