Answer 1

By selling a pen gain is Rs.2

and by selling  pencils, he loses 50 paise

and an eraser, he loses 15 paise

On one day, he gains =Rs.10

On that day he sold 10 pens and pencils and erasers in the ratio of 7:10

On ten pens, his gain =10×2=Rs.20

loss on pencils and erasers =Rs.20−Rs.10=Rs.10=1000 paise

the Ratio in pencil and eraser =7:10

Let the number of pencils =7x, then eraser =10x

7x×50+10x×15=1000

⇒350x+150x=1000

⇒500x=1000

⇒x=2

Number of pencils =7×2=14

and number of erasers =10×2=20

hope it helps
