In a very famous game known as "Clash Royal", There is a very powerful warrior named "The Wizard" which can be purchased from the card shop.
Cost increases in an interesting manner i.e
Cost of 1st Wizard is: 50 coins
Cost of 2nd Wizard is: 100 coins
Cost of 3rd Wizard is: 150 coins
Cost of 4th Wizard is: 200 coins
Cost of 5th Wizard is: 250 coins
i.e to buy 5 wizrds you need 50+100+150+200+250 = 750 coins.
How many wizards can you buy using 10000 coins ?
