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 - 16 men and 20 boys can do a piece of work in 30 days. In how many days, 15 men and 15 boys will take to finish the work?

Options :

E - Other than the given options

Answer : A

Explanation

16 men = 20 boys

1 man = 5/4 boys

15 men = 75/4 boys

Total no of boys = 75/4 + 15 = 135/4

20 boys = 30 days

135/4 boys = 30 × 20 × 4 /135 = 17 7/9 days

Q 7 - July 28 is my birthday and I usually distribute rasagollas to my friends on that eve. I have a few rasagollas to be distributed. If I keep 2, 3 or 4 in pack, I am left with one Rasagolla. If I keep 5 in a pack, I am left with none. What is the minimum number of rasagollas I have to pack and distribute?

Options :

Answer : A

Explanation

By packing 5 rasagollas in a pack, we would be left with no extra ones.

So, the total number of Rasagollaas is obviously divisible by 5.

This eliminates the option C.

By packing 2,3, or 4 Rasagollas in a pack, we are left with 1 rasogolla

So, (the number of Rasagollas -1) must be divisible by 2,3, and 4

In case of option A, (25 - 1 = 24) is divisible by 2, 3, and 4.

In case of option B, (35 - 1 = 34) is divisible by 2 but is not divisible by 3 and 4. So, this eliminates option B.

In case of option D, (65 - 1 = 64) is divisible by both 2 and 4, but, is not divisible by 3. This eliminates option D also.

So, the only eligible option left with us is 25.

So, option A would be the answer.

Q 8 - Raju Khandelwal is twice as good a workman as Neeraj Behera and together they finish a piece of work in 18 days. In how many days can Raju alone finish the work?
