If 2500 is to be divided among ravi, raju and roy, so that ravi gets two parts, raju has
three parts and roy five parts. how much money will each get? what will it be in percentages?

The money each will get are 500 to Ravi , 750 to Raju and 1250 to Ravi. And there percentages are Ravi's 20%, Raju's 30% and Roy's 50%.

Step-by-step explanation:

Given:

2500 is to be divided among Ravi, Raju and Roy, so that Ravi gets two parts, Raju has  three parts and Roy five parts.

Now, to find the money each will get and the percentages of it.

Let the price of one part be

The price of two parts be

The price of three parts be

And the price of five parts be

According to question:

Dividing both sides by 10 we get:

Ravi gets two parts =

Raju gets three parts =

Roy gets five parts =

Now, the percentage of the money they get:

Percentage of Ravi's share:

Percentage of Raju's share:

Percentage of Roy's share:

Therefore, the money each will get are 500 to Ravi , 750 to Raju and 1250 to Ravi. And there percentages are Ravi's 20%, Raju's 30% and Roy's 50%.

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
