The pie chart shows the favourite sports of a group of students.

If 34 students like hockey, then calculate the total number of students who like lawn tennis and table tennis.

Sum of percentages $=18+5+32+28+x=100$ 

$x=17\%$

$17\%$  of total students = 34

$\frac{17}{100}\times \text{ total students = 34}$

Total students = $34\times \frac{100}{17}=200$

The No. of students who like Lawn tennis  & table tennis $=18\%\text{ of }200+28\%\text{ of 200}$

$=36+56=92$
