Three digit number will have unit?s, ten?s and hundred?s place.
Out of 5 given digits any one can take the unit?s place.
This can be done in 5 ways. ... (i)
After filling the unit?s place, any of the four remaining digits can take the ten?s place.
This can be done in 4 ways. ... (ii)
After filling in ten?s place, hundred?s place can be filled from any of the three remaining digits.
This can be done in 3 ways. ... (iii)
So,by counting principle, the number of 3 digit numbers = 5x 4 x 3 = 60
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
