In a Certain Country 1/2 of 5 = 3. If the same proportion holds, what is the value of 1/3 of 10 ?

A) 4	B) 6

Explanation:

Let $\frac{1}{3} (10) = x$

=> 3x = 10

Given that $\frac{1}{2} (5) = 3$

Q:

A train travelling with a speed of 60 km/hr catches another train travelling in the same direction and then leaves it 120m behind in 18 seconds. The speed of the second train is

A) 42 kmph	B) 72 kmph
C) 36 kmph	D) 44 kmph

Answer & Explanation Answer: C) 36 kmph

Explanation:

Given speed of the first train = 60 km/hr = 60 x 5/18 = 50/3 m/s

Let the speed of the second train = x m/s

Then, the difference in the speed is given by

$\frac{50}{3} - x = \frac{120}{18}$

=> x = 10 m/s

=> 10 x 18/5 = 36 km/hr

Q:

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

Everyone expected Mary Zophres to win for her retro-revival Technicolor clothes in La La Land — the eventual winner, Colleen Atwood for Fantastic Beasts and Where to Find Them, seemed surprised too. But as other awards began to slip away from the well-reviewed musical, a theme could be teased out. What is Fantastic Beasts if not a plea for equal treatment of people, magical or otherwise? Then, Arrival, a film about the inherent benignity of aliens (read immigrants) won for Best Sound Editing. Hacksaw Ridge, which is, in a way, an anti-guns movie, won in two categories. Fences, about an African-American father who fears racial discrimination, took home the Oscar for Best Supporting Actress. Earlier, Moonlight, featuring two minority communities (black and gay), won for Best Supporting Actor. This turned out to be one of those years the Oscar voter was underestimated. As a majority of voters are actors, there was the tendency to think they'd reward La La Land, a celebration of creation: the heroine wants to make movies, the hero wants to make jazz. It looked like the year of The Artist all over again.

Why was it assumed that La La Land would win a lot of awards?

A) Because the movie celebrates creation	B) Because majority of voters are actors
C) Because it is a movie about making movies and jazz	D) Because it is a retro-revival Technicolor movie

Answer & Explanation Answer: B) Because majority of voters are actors
