Answer 1

Answer:

30&60,8.5/-

Step-by-step explanation:

1.Incorrect question

2.Let the no. of 50paise coins be x& 25paise coins be 2x.

Then, amount got from 50paise coins=0.50x/-

Then, amount got from 25paise coins=0.25×2x=0.50x/-

According to the question

0.5x+0.5x=30

Or,x=30=no.of 50paise coins

Or,2x=30×2=60=no.of 25paise coins

3.Let the CP of pen be x/-

Then,5x=3x+17

Or,5x-3x=17

Or,2x=17

Or,x=17/2=8.5/-
