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
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

a) 2
b) 5/2
c) 3
d) 4/5
Answer: A)

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)
Explanation:
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.
Therefore
the next number in the sequence will be = 12
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)
Explanation:
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
