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 :

A - 1299

B - 1099

C - 1899

D - 2499

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.

Options :

A - 28

B - 35

C - 32

D - 14

Answer : C

Explanation

5 women or 8 girls can do the work in 84 days.

1 woman can do the work in 5 × 84 = 420 days.

1 woman’s 1 day work = 1/420

1 girl can do the work in 8 × 84 = 672 days.

1 girl’s 1 day work = 1/672

Work done in one day by 10 woman and 5 girls would be

$10*\frac{1}{420}+5*\frac{1}{672} \: = \: \frac{1}{32}$

The total amount of time taken would be the reciprocal of the total work done = 32 days.
