Let the CP be 100 and % mark up be k% then
MP = 100 + k
100 + k is also expected SP but actual SP = 100 + k / 2
? [(100 + k / 2)] / k = (200 / 3) x 100 (= 66.66%)
? k = 300
? CP = 100 and MP = 400
Finally SP = 400 / 2 = 200
? Discount = 200 / 400 X 100 = 50%
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
