1. 90
2. 105
3. 100
4. 110

Answer 1

Correct Answer - Option 3 : 100

Given

Average score of cricketer in 10 innings is 56

After 11 inning his average increases by 4

Formula used

Average = sum of observation / number of observation

Calculation

Average in 10 innings = 56

⇒ Total runs in 10 innings = 56 × 10 = 560

⇒ After 11 inning average becomes 56 +  = 60 

⇒ Total runs in 11 innings = 60 × 11 = 660 runs

∴ His run in 11th inning is 660 - 560 = 100 runs
