If a pie-chart is drawn representing the number of students in all five colleges, what is the central angle (correct to the nearest whole number) of the sector representing the students of college B?
Solution
From the above table, The number of students are available in college A$$ = 950$$ The number of students are available in college B $$= 1200$$ The number of students are available in college C $$= 850$$
The number of students are available in college D $$= 975$$ The number of students are available in college E $$= 1025$$
Hence, total number of students are available in the class $$= 5000$$
so percentage of area occupy by college B $$\dfrac{1200\times 100}{5000}=24\%$$
which occupy 24% of the area in the pie graph.
Hence angle $$=\dfrac{24\times360}{100}=86.6^\circ$$ So, it will be approximately $$86^\circ$$

In 2017 the sales of each brand increased by the same percentage as it did in the year 2016. What will be the approximate average sales (in units) of mobiles per brand in year 2017?
Solution
Increase in sales of brand 1 in 2016 = $$\frac{7.5-5.5}{5.5}\times100=36.36\%$$
=> Sales of brand 1 in 2017 = $$7.5+(7.5\times\frac{36.36}{100})=10.2$$
Increase in sales of brand 2 in 2016 = $$\frac{6-5}{5}\times100=20\%$$

Expenditure on education = $$\frac{70}{360} * 360x = 70x$$
Expenditure on housing = $$\frac{54}{360} * 360x = 54x$$
=> Required difference = $$70x - 54x$$ = 1600
=> $$x$$ = 100
Expenditure on food = $$\frac{120}{360} * 360x = 120x$$
=> 120*100 = 12000
