Siva had some money. After spending $10 on 3 writing pads and 7 penscils, he would be short of $0.40 if he were to buy another writing pad. However, if he were to buy 1 more pencil, he would have $0.60 left. How much did each writing pad cost ?

There was a similar type of question in one of the earlier posts.
