? S.P of the notebook = ?457
? Commission on one notebook = ? (4 x 457)/100
and commission on 10 notebooks = 10 x (4 x 457)/100 = ? 18280
Now,S.P of the pencil box = ? 80
? Commission on 1 pencil box = ? (80 x 20)/100
Commission on 6 pencil boxes = (80 x 20 x 6)/100 = ? 96
Hence ,total commission of 1 day = (182.80 + 96 ) = ? 278.80
Thus, total commission of 2 weeks = 278.80 x 14 = ? 3903.20
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
