How many numbers are there between 100 and 300 which either begin with or end with 2?1. 1102. 1113. 1124. None of the above

Answer» Correct Answer - Option 1 : 110

Calculation 

⇒ From 100 to 199 , total number ends with 2 are 102, 112 ......192  = 10 

⇒ From 200 to 299 , total number ends or begin with 2 are 201, 202 ....299 = 100 

⇒ so total number are there between 100 and 300 which either begin or end with 2 = 100 + 10 =110 

∴ 110 numbers are there between 100 and 300 which either begin with or end with 2
