• # question_answer Raghu has enough money to buy 75 machines worth Rs. 200 each. How many machines can he buy if he gets a discount of Rs. 50 on each machine? A)  180                            B)         200    C)         150                            D)         100

More the cost of machines, lesser the number of machines bought. So, it is a case of inverse proportion. Hence, $75\times 200=y\times 150$ Or $y=\frac{75\times 200}{150}=100$
