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?
Let age of Anil and Puskar is x & 50-x
Age of Sameer = y

Q 2 - A college organised a function in which 1/3rd of boys and ½ of girls are present. Total number of students present is
Number of boys and number of girls are not given.
Q 3 - Ronit Kumar can cover a distance in 1hr 24min by cycling by covering two third of the distance at four kilometre per hour and rest at a speed of one kilometre more than the previous. Find out the total distance.
Distance = (2/3) S
distance = 1-2/3 S = (1/3)S
21/15 hr = (2/3) S/4 + (1/3) S /5
84 =(14/3)S x 3
S = 6km.
Q 4 - Two friends Ajit and Sujit are working on a project for educational purposes for students between class 6th to 10th. Ajit takes 6 hours to type 32 pages on a computer, while Sujit takes 5 hours to type 40 pages.

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?
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 - There are 75 coins in a bag which contains only 25 paise and 50 paise coins. The value of the coins is 25. Find the numbers of 25 paise coins.
Let the number of 25 paise coins be x. Then number of 50 paise coins will be (75-x).
X × 0.25 + (75-X) × 0.50 = 25
0.25X + 37.50 - 0.50x = 25
0.25x = 12.50
X = 12.50/0.25 = 50
Q 7 - Piyush Goyal has Rs. 960 in the denominations 10 rupee notes, 5 rupee notes, 1 rupee notes. The number of each denomination is equal. What is the total number of notes that he has?
Let number of notes of each denomination be x.
Then x + 5x + 10 = 960.
16 x = 960 = x = 60.
Hence, total number of notes = 3x = 180.
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
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 - Akshay takes 8 hours to do a job. Ahmed takes 10 hours to do the same job. How long it take both Akshay and Ahmed, working together but independently, to do the same job?
Akshay's one hour work = 1/8. Ahmed's one hour work = 1/10. (Akshay + Ahmed)'s one hour work = 1/8 + 1/10 = 9/40. Both Akshay & Ahmed can finish the work in 40/9 days.
Q 10 - In a bucket there are 45 fishes. This bucket is added into another bucket which already contained 87 fishes. If all the fishes are to be stored in 12 different small buckets then each small bucket will contain how many fishes?
Total no of fishes in big bucket is 45 + 87 = 132. 132/12 = 11. So each small bucket will contain 11 fishes.
