Question

Please the traffic during office hours Rises 20% in the morning during the daytime it falls 20% what is the net rise or fall in traffic

Answer 1

Answer:

4% fall

Step-by-step explanation:

Let the no. of vehicles initially be 100

The increase in no. of vehicles during daytime will be 20% of 100 = 20

So now the new no. of vehicles is 120.

The fall in no. of vehicles during evening is 20% of 120 = 24

So now, the no. of vehicles is 96.

∴ There is a net 4% decrease in traffic.
