Given: Ravi gets 61% of the total valid votes Total votes = 25000 20% of the total votes were declared invalid Calculation: Total votes = 25000 ⇒ Invalid votes = 20% of 25000 = 5000 ⇒ Valid votes = 25000 - 5000 = 20000 Ravi gets 61% of the total valid votes ⇒ Manoj gets 39% of the total valid votes ∴ Number of votes Manoj gets = 20000 × (39/100) = 7800
