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 ?

Explanation

Cost of 1 machine = `Rs.200`
Cost of 75 machines
`200xx75`
`15000`
Now he gets a discount of `Rs. 50` on each machine
So, Cost of 1 machine =`Rs.200`-`Rs.50`=`Rs.150`
No. of machines can be bought by `Rs.150 =1`
No. of machines can be bought by
`Rs 1 =1/150`
No. of machines can be bought by
`Rs.15000 =(1/150)xx15000`
`100`
