Given:

No of bats manufactured in 2010 = 3000 

Percentage of unsold bats in 2010 = 20%

No of bats manufactured in 2014 = 3500 

Percentage of unsold bats in 2014 = 24%

Calculation:

No of sold bats in 2010 = (100 - 20)% × 3000 

⇒ 80/100 × 3000 

⇒ 2400

No of sold bats in 2014 = (100 - 24)% × 3500 

⇒ 76/100 × 3500 =  2660

∴ The difference between the number of bats sold in 2014 and 2010 

⇒ 2660 - 2400 

⇒ 260
