A girl want to read a complete book. She read 2/5 part of a book on 1st day, 34% on second day and remaining pages in next two days. On those two days she read equal number of pages. If she read 52 pages on last day, then find out total number of pages that the book contain ?

4th observation i.e., 8 is the median.

47/10000 = .0047

.02 =(2/100) x 100% =2%

Let N / 11 = 233
Then, N = 233 x 11 = 2563
? Missing digit is 5.

121012 = 12 x 10084 + 4
? remainder = 4

We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days

? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
