1. 18
2. 16
3. 20
4. 22

Answer 1

Correct Answer - Option 3 : 20

Given:

Average runs of player in 20 matches = 35

Average runs of player in first 12 matches = 45

Formula:

Average = (Sum of all observations)/(Total number of all observations)

Calculation:

Sum of runs of player in 20 matches = 35 × 20 = 700

Sum of runs of player in first 12 matches = 12 × 45 = 540

Sum of runs of player in last 8 matches = 700 - 540 = 160

∴ Average runs of player in last 8 matches = 160/8 = 20
