What is the average of a and e?

The average of a, b, c, d, and e is 28. If the average of a, c, and e is 24, what is the average of b and d?

The average of A and B is 400 and the average of C and D is 600 the average of A,B,C and D is:

Let a, b and c be numbers with altbltc such that the average of a and b is 2, average of b and c is 4, and the average of a and c is 3. What is the average of a, b and c?

The average of a,b, and c is 79 and the average of a and c is also 79.then the value of b is:

If the average (arithmetic mean) of k and k+7 is b and if the average of k and k-11 is c, what is the sum of b and c?

The average of a, b, c, and d is p. If the average of a and c is q, what is the average of b and d in terms of p and q?

The average age of A, B and C is 26 years. If the average age of A and C is 29 years, what is the age of B in years ?
