Given Dileep and Narender started a business.
Dileep invested 8000 for 12 months
Let Narender invested 'p' for 6 months
At the end of the year, their profit ratio is 1 : 1.
Hence,
8000 x 12 : p x 6
p : 16000
p/16000 = 1/1
=> p = 16,000
Hence, Narender invested amount is Rs. 16,000.
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
