Q:

Two electric bulbs marked 25W – 220V and 100W – 220V are connected in series to a 440Vsupply. Which of the bulbs will fuse?

A) 25 W	B) Both
C) 100 W	D) Neither

Answer & Explanation Answer: A) 25 W

Explanation:

Resistances of both the bulbs are

R1=V^2/P1 = 220^2/25

R2 = V^2/P2 = 220^2/100

Hence $R 1 g t; R 2$

When connected in series, the voltages divide in them in the ratio of their resistances. The voltage of 440 V devides in such a way that voltage across 25 w bulb will be more than 220 V. Hence 25 w bulb will fuse.

Q:

The ratio of cost price and marked price of an article is 2:3 and ratio of percentage profit and percentage discount is 3:2 . what is the discount percentage?

A) 16.66%	B) 20%
C) 25%	D) 33.33%

Answer & Explanation Answer: A) 16.66%

Explanation:

CP : MP = 2x : 3x

=> Profit = x

( %) profit : (%) discount = 3:2

Let CP = 2000, SP = 300

But $\frac{3 x}{100} \times 200 + \frac{2 x}{100} \times 300 = 100$

=> x = 8.33%

Discount 2x = 16.66%

Q:

A fort had provision of food for 150 men for 45 days. After 10 days, 25 men left the fort. The number of days for which the remaining food will last, is:

A) 29/5	B) 37/4
C) 42	D) 54

Answer & Explanation Answer: C) 42

Explanation:

After 10 days : 150 men had food for 35 days.

Suppose 125 men had food for x days.

Now, Less men, More days (Indirect Proportion)

125 : 150 :: 35 : x => 125 x x = 150 x 35

=>

=> x = 42.
