Let total profit = N
Paid to charity = 9% of N = 9N/100
? Balance profit = N - (9N/100) = 91N/100
? A's share = [4/(4 + 3)] x (91N/100) = (4/7) x (91N/100)
According to the question,
(4/7) x (91N/100) = 1196
? N = (1196 x 7 x 100)/(4 x 91) = ? 2300
Hence, total profit = ? 2300
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
