Ashu's mother was three times as old as Ashu 5 yrs ago. After 5 yrs, she will be twice as old as Ashu. How old is Ashu today?

Detailed Solution for RRB Group D Mock Test - 19 - Question 1

(x + 5) = 2 (y + 5)

A printer numbers the pages of a book starting with 1 and uses 3189 digits in all. How many pages does the book have?

Detailed Solution for RRB Group D Mock Test - 19 - Question 79

No. of digits in 1-digit page nos. = 1 x 9 = 9.
No. of digits in 2-digit page nos. = 2 x 90 = 180.
No. of digits in 3-digit page nos. = 3 x 900 = 2700.
No. of digits in 4-digit page nos. = 3189 - (9 + 180 + 2700) = 3189 - 2889 = 300.
Therefore No. of pages with 4-digit page nos. = ( 300/4 ) = 75.
