Percentage · solved example
In an election between two candidates, the winner secured 60% of the valid votes and won by 900 votes. Find the total number of valid votes.
Solution
The winner got 60% and the loser 40%, a margin of 20% of the votes. If 20% = 900, the total is 900 ÷ 0.20 = 4500.
Percentage · solved example
Find 60% of 350.
Solution
60% of 350 = 0.6 × 350 = 210.
Time, speed and distance · solved example
A train 200 m long runs at 72 km/h. How many seconds does it take to cross a pole?
Solution
72 km/h = 20 m/s, so time = 200 ÷ 20 = 10 seconds.
Profit and loss · solved example
An article bought for Rs 250 is sold for Rs 300. Find the profit percent.
Solution
Profit = 50 on a cost of 250, so profit percent = 50/250 × 100 = 20%.
