The average of 11, 12, 13, 14 and x is 13. The value of x is ........
1 17
2 21
3 15
4 20
Explanation:
15 The average of 11, 12, 13, 14 and x is 13 \(\therefore\frac{11+12+13+14+{\text{x}}}{{5}} = 13\) \(\therefore 50+{\text{x}} = 65{\text{x}} = 15\)

The arithmetic mean of 5 numbers is 27. lf one of the number is excluded the mean of the remaining number is 25. Find the excludednumber:
1 27
2 25
3 30
4 35
Explanation:
35 Sum of 5 numbers = 27 × 5 = 135 when one of the numbers is excluded. sum of remaining 4 numbers = 4 × 25 = 100 Excluded number = 135 - 100 = 35.

M= 1, 2, 3, 4, 5, 6, 7. Each number in set N is generated by dividing each number in set M by 2. Calculate the arithmetic mean of numbers in N:
1 1
2 \(\frac{3}{2}\)
3 \(\frac{7}{4}\)

Explanation:
2 Given, M = 1, 2, 3, 4, 5, 6, 7 Each number in set N is generated by dividing each number in set M by 2 N = 0.5, 1, 1.5, 2, 2.5, 3, 3.5 Arithmetic mean of numbers of set N is \( = \frac{0.5+1+1.5+2+2.5+3+3.5}{7} = \frac{14}{7} = {2}\)
