UPSC CAPF Assistant Commandant Model Paper 3

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
