Candy

The price for 1kg of more expensive candy is 125 CZK. The price for 1kg of cheaper candy is 100 CZK. We make two different blends of candy. And now. The second blend contains 2kg of more expensive candy and several kg of cheaper candy. The price per 1 kg of this mixture is 110 CZK. Calculate how many kilos of cheaper candy contains the second blend.

Result

x =  3

Solution:


2*125+x*100=110*(2+x)

10x = 30

x = 3

Calculated by our simple equation calculator.
