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  R1gt ; R2

 

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  3x100×200 + 2x100×300 = 100

 

=>  x = 8.33%

 

Discount 2x = 16.66%

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

 


Many plays and films have depicted the life story of Gautama Buddha, but what made the musical play The Way Across unique was its regional focus. Directed by G. Kumara Swamy, the play adapted from the book Telangana lo Buddhism focused on the enlightenment of a cursed Brahmin Bawari and his 16 curious disciples willing to understand the deeper truths of birth, death, rebirth and brotherhood.

 

From the impressive use of projector visuals, music and shadow-play, there was every effort to lend authenticity to the theme. Despite the play's focus on Telangana, the native essence was compromised, due to the English rendition (done for a wider reach). The lines appeared jaded with literal translations. The honest performances from the crew impacted only on a surface-level. Kiran Kumar's Bawari act and Krishna Chaitanya Joshi as Pingiya (said to have propagated Buddhism from Telangana to several regions across South India) grab your attention.

 

What was unique about the play, 'The Way Across'?

A) Story line B) Regional focus
C) It was a musical D) It was in English
 
Answer & Explanation Answer: B) Regional focus
