Answer:
By selling a pen gain is Rs.2
and by selling a pencils, he loses 50 paise
and an eraser, he loses 15 paise
On one day, he gain =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
Ratio in pencil and eraser =7:10
Let number of pencils =7x, then eraser =10x
7x×50+10x×15=1000
⇒350x+150x=1000
⇒500x=1000
⇒x=2
Numbe rof penciles =7×2=14
and number of erasers =10×2=20
