A certain sum is divided among P, Q and R such that P gets 775 more than one-fourth of the sum, Q gets 512 less than two-fifth of the sum and finally R gets 3510. What is the total sum?(1) 10,045 (2) 7,550(3) 8,780 (4) 9,610(5) None of these

Answer»

Let the sum be x

P get = 1/4 of x + 775

Q get = 2/5 of x - 512

R = 3510


P + Q + R = sum

x/4 + 775 + 2x/5 - 512 + 3510 = x

x - x/4 - 2x/5 = 3773

(20x - 5X - 8X) / 20 = 3773

7x = 75460

x = 75460/7

x = 10780


so sum was 10780

Help Explain how to calculate Give one example of each._________Thank you ☺☺

Answer»

]\textbf{hey mate here is ur <klux>ANSWER</klux>}....

1. mean - The mean is the average of the numbers.

To calculate :-   1. add  all the numbers.

2. then divide by how many numbers there are.

example :- find mean of 5, 10, 20, 15 , 30

= 5+ 10 + 20 + 15 + 30/4

= 80 / 5

= 4

so, the mean = 4



2. median :- The Median is the "middle" of a sorted list of numbers.

To calculate :- 1. Put all the numbers in numerical order.

2. If there is an odd number of results, the median is the middle number.

3. If there is an even number of results, the median will be the mean of the two central numbers.

example :- 1. in case of odd,

find median of 10, 15, 20, 30 ,5

step 1 :- put them in ascending order .

step 2 :- 5, 10, 15 , 20, 30

step 3 :- here the middle no is 15.

so, 15 is the median.


2. in case of even,

10, 15, 20, 30

step 1 :- put them in ascending order.

step 2:- 10, 15, 20, 30

step 3 :- here middle no is 15 and 20.

step 4 :- add these no.

step 5 :- 35

step 6 :- divide it by 2

step 7 :- 35 / 2 = 17.5

so, 17.5 is the median.


3. Mode :- the value that OCCURS maximum times.

To calculate :- step 1 :- put them is ascending order .

step 2 :- find the value which occurs maximum times.

example :- 13, 18, 13, 14, 13, 16, 14, 21, 13

step 1 :- 13, 13, 13, 13, 14, 14, 16, 18, 21

step 2 :- 13 occurs maximum times.

so, 13 is the mode.


4. probability :- Probability means the chance or the likelihood of occurrence of an event.

example :- A jar contains 4 blue marbles, 5 red marbles and 11 white marbles. If a marble is drawn from the jar at random, what is the probability that this marble is red?

answer :- The number of events is FIVE (since there are five red marbles), and the number of outcomes is 20. The probability is 5 ÷ 20 = 1/4 .
