Three different numbers are chosen such that when each of the numbers is added to the average of the remaining two, the number 65, 69 and 76 are obtained. The average of the three original numbers is

The average of 8 numbers is 14. The average of 6 of these numbers is 16. What is the average of the remaining two numbers?

a,b,c are three numbers such that the average of a and b is 4, that of b and c is 5 and that of a and c is 12. The average of all the three numbers is :

If p, q, r be three positive numbers such that p gt q gt r . when the smallest number is added to the difference of the rest two number, then the average of the resultant number and the original numbers except to the smallest number is 21 more than the average of all the three original numbers . Find the value of (p – q).

If p, q, r be three positive numbers such that p gt q gt r when the smallest number is added to the difference of the rest two numbers, then the average of the resultant number and the original numbers except to the smallest is 21 more than the average of all the three numbers. The value of (p-q) is :
