Question 63

The following table shows a survey conducted in the schools of a city. This survey shows the type of activities teenagers (age 13 to 19 years) are involved in during their leisure time.

If a teenager has 6 hours of leisure time in a day, then how much time does he/she spend daily on net surfing?

Solution

If a teenager has 6 hours of leisure time in a day.

leisure time in a day = (25+30+20+20+5)% = 6 hours

100% = 6 hours

1% = $$\frac{6}{100}$$ hours

Time does he/she spend daily on net surfing = 20% = $$\frac{6}{100}\times20$$ hours

= $$\frac{6}{5}$$ hours

= 1.2 hours

[1 hour = 60 minutes, then 0.2 hours = $$0.2\times60$$ minutes = 12 minutes]

= 1 hour 12 minutes
