Question

The adjoining figure shows the food liking of 1080 students of a school. Read this graph and answer the following questions:

$\left(a\right)$ How many students like chapatis?

$\left(b\right)$ How many students like rice?

$\left(c\right)$ How many students like dosa more than pizza?

$\left(d\right)$ What percentage of students like pasta?

$\left(e\right)$ If the number of students m the school increases $1200$, how many more pizzas will be needed if each student eats only one pizza?

Answer 1

a) $\frac{120}{360}\times 1080=\frac{1080}{3}=360$

b) $\frac{90}{360}\times 1080=\frac{1080}{4}=270$

c) $\frac{60}{360}\times 1080=\frac{1080}{6}=180$

d) $\frac{45}{360}\times 100=\frac{100}{8}=12.5$%

e) No. of pizza initially needed $=\frac{45}{360}\times 1080=\frac{1080}{8}=135$

No. of pizza reqd of no. of stud is $120=\frac{45}{360}\times 1200=\frac{1200}{8}=150$

$\therefore$ $15$ more pizzas are required.
