Given:

Average of 5 numbers = 4

2 is added to each number.

Formula:

Average = Sum of numbers ÷ Number of numbers

Original Sum = 4 × 5 = 20

After adding 2 to all 5 numbers:

New Sum = 20 + (2 × 5) = 30

New Average = 30 ÷ 5 = 6

Explanation

Average of 10 values = 200

Total sum = Average × Number of values

= 200 × 10

= 2000

Sum of 9 values = 1850

10th value = 2000 − 1850 = 150
