Direction: In the question, two Quantities I and II are given. You have to solve both the Quantity to establish the correct relation between Quantity-I and Quantity-II and choose the correct option.
Quantity-I: The selling price of an article when it is marked 36% above its cost price and sold after a discount of Rs. 140 is Rs. 'P' and the selling price of the same article when it is marked 28% above its cost price and sold after a discount of Rs. 120 is Rs. 'Q'. If P : Q = 19:18, then find the cost price of the article.
Quantity-II: The compound interest received on investing Rs. 10,500 for 2 years at 'y%' p.a., compounded annually is Rs. 2,205. Find the compound interest received on investing Rs. 4,800 at a rate of (y + 5) % p.a., compounded annually for 2 years.
