Answer 1

Answer:

We've to find the option ,which is the 2/5 of the total pie chart

that is the total is 100%

$\frac{2}{5} \times 100 \\ \frac{200}{5} \\ = 40$

therefore 2/5 of the total data is 40%,

that is the answer will also be of 40%

here from the figure

we've to find out which is the 40%

and that is

option a) Food and others (30+10=40%)

Let's check whether it's correct or

$\frac{40}{100} = \frac{2}{5} \\ \frac{20}{50} = \frac{2}{5} \\ \frac{2}{5} = \frac{2}{5}$

L.H.S=R.H.S

hence verified

hope it helps
