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.

Options :
Answer : B

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

Options :
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.
