Q 1 - Sameer is much young as Anil as he is older to Puskar. If sum of ages of Anil and Puskar is 50 years. What is age of Sameer?

Options :

Answer : C

Let age of Anil and Puskar is x & 50-x

Age of Sameer = y

x-y = y-(50-x)y = 25

Q 2 - A has $3 more than B, but then B wins on the horses and trebles his money, so that he now has $2 more than the original amount of money that the two boys had between them. How much money did A and B have before B's win?

Options :

Answer : B

Explanation

Let money with A = x. Then, money with B = x + $3. Now, 3x = (x + x + $3) + $2 x = $5.

Therefore total money with A and B = 2x + $3 = $13.

Q 3 - In between two file ends in the rack are six paper weights. If you decide to arrange the six paper weights in every possible combination and moved just one paper weight every minute, how long would it take to you?

Options :

Answer : A

Explanation

Clearly, we can get the answer by taking the factorial.

= 6! = 6 × 5 × 4 × 3 × 2 × 1 = 720.

So total time taken = 720 minutes = 12 hours.

Q 4 - Two trains are running from Jamshedpur and Kanpur towards each other. Train from Jamshedpur takes 2 hours more than that of the train from Kanpur in covering a distance of 30 km. If Jamshedpur train doubles its speed, then it would take 1 hour less than that of Kanpur. Jamshedpur train’s speed is?

Options :

Answer : A

Explanation

Let Jamshedpur train's speed be a km/hr. Then, according to the question if we put it in a mathematical formula then (30/a) – (30/2a) = 3

6a = 30

a = 5 km/hr.

Q 5 - For making a project, Rajiv took printouts of his soft copy from a printer and the printer numbers the pages of a book starting with 1 and uses 4089 digits in all. How many pages does the book have?

Options :

Answer : A

Explanation

Number of digits in single numbered pages of the book = 9 × 1 = 9.

No. of digits in double numbered pages of the book = 2 × 90 = 180.

No. of digits in triple numbered pages of the book = 3 × 900 = 2700.

No. of digits in quadruple numbered pages of the book = 4089 - (9 + 180 + 2700) = 4089 - 2889 = 1200.

Therefore number of pages with 4-digit page numbers = (1200/4) = 300.

Hence, total number of pages = (999 + 300) = 1299.

Q 6 - The average age of 13 persons is 36 years. If he age of one more person is added the average decreases by half a year. What is the age of the new person?

Options :

Answer : A

Explanation

Total age of 13 persons = 36 × 13 = 468

Total age of 14 persons = 35.5 × 14 = 497

Age of the new person = 497 - 468 = 29 years

Q 7 - In my kitchen room between two partitions ends, there are four containers containing my favourite snacks. If I decide to arrange the four containers in every possible combination and move just one container every minute, how long would it take me to do the job?

Options :

Answer : A

Explanation

Clearly, number of ways arranging four containers,

= 4! = 4 × 3 × 2 × 1 = 24.

So total time taken = 24 minutes.

Q 8 - Rajdhani express runs from Bhubaneswar to Delhi. At some point during the journey it covers a distance in 50 min, if it runs at a speed of 48kmph on an average. The speed at which Rajdhani express must run to reduce the time of journey to 40min will be

Options :

Answer : B

Explanation

Time = 50/60hr = 5/6hr Speed = 48 kmph distance = S × T = 48 × 5/6 = 40 km time = 40/60hr = 2/3hr New speed = 40 × 3/2 kmph = 60kmph

Q 9 - An auto can pick 5 people at a time. A minibus can pick 20 people at a time. One day 7 buses came one after another. How many autos are required to take the people away from the spot?

Options :

Answer : C
