$\bf Price \: of \: 50 \: pencils = 100 \frac{1}{5} = 20 \: rs \\ \\ \bf Price \: of \: 1 \: pencil = \frac{20}{50} = 0.4 \: rs$

Answer 2

Answer:

here is ur answer

Step-by-step explanation:

let pen be x and pencil be y

100x=500*3/5 =>100x=100*3 =>100x=300

=>x=300/100  =>x=3

50y=100*1/5  =>50y=20 =>y=20/50  =>y=2/5

3 pen =3*3=9

5 pencil =5*2/5=2

3 pens price is 9 and 5 pens price is 2
