Question

The following pie chart shows the percentage of time allotted for various activities in a school. How much time is allotted for critical thinking and reading together if the total time given for all these activities is 25 hours in a week?

• A. 9 h
• B. 3 h
• C. 5 h
• D. 8 h

Answer 1

The correct option is D 8 h

The total time given for all activities is 25 hours.

Let us consider the time taken for these activities is 100%.

Percentage allotted for critical thinking = 100 – Sum of percentage of time taken by all the other activities

$=100\%–(25+20+18+25)\%$

$=100\%–88\%$

$=12\%$

∴ Time allotted for reading = Total time × % of time for reading

$=25\times \frac{20}{100}$

$=5\text{hours}$

∴ Time allotted for critical thinking = Total time × % of time for reading

$=25\times \frac{12}{100}$

$=3\text{h}$

So, time allotted for both critical thinking and reading together = 5 + 3 = 8 h
