Let food stock will be exhausted in x days .
Given, m1 = 120, D1 = 45
M2 = 120 + 30 = 150
and D2 = ?
Then, using M1D1 = M2D2
? 120 x 45 = 150 x D2
? D2 = 120 x 45/120 = 36
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
