1. An article was purchased for Rs. 17,520. Its price was marked up by 50% on the cost price. It was sold at a discount of 20% on the marked up price. What was the profit percent on the cost price?
a) 20
b) 16
c) 18
d) 15
Answer: A)
Explanation: Cost price of the article = Rs. 17520
It is marked up by 50%
Marked price of the article,
17520 + 17520 × 50/100 = Rs.26280
Discount given = 20%
Discounted price = 26280 26280 × 20/100 = Rs.21024
Profit = 21024 – 17520 = Rs. 3504
Profit percent = 3504/17520 * 100 = 20%
2. If tan x = 1 , then the value of : (8 sin x + 5 cos x)/(sin^3 x – 2 cos^3 x + 7 cos x) is
a) 2
b) 5/2
c) 3
d) 4/5
Answer: A)
Explanation: Given tanx = 1 => x = 45°

4. The product of three consecutive even numbers is 960. The product of the first and the second number is 80. What is eight times the third number?
a) 96
b) 100
c) 88
d) 92
Answer: A)
It's given that product of first two numbers is 80. This clearly implies that the two consecutive even numbers have to be 8 and 10.

and 8 times of 12 = 96
5. Top of two poles of height 48 m and 72 m are connected by a wire. If the wire makes an angle of 60° with the horizontal surface, then the length of wire is:
a) 12
b) 16√3
c) 12√3
d) 16
Answer: B)

DE = 72 – 48 = 24
from Δ ADE,
sin 60° = DE/AD
√3/2 = 24/AD
=> AD = (24 * 2)/ √3 = (3 * 8 * 2)/ √3 = 16√3
