Answer:
Let the cost of one pen is x and the cost of one berk is y
Given, the cost of 6 pens and 8 berks is equal to the cost 3 pens and 10 berks
=> 6x + 8y = 3x + 10y
=> 6x + 8y - 3x = 10y
=> 3x + 8y = 10y
=> 3x = 10y - 8y
=> 3x = 2y
=> 2y = 3x
=> y = 3x/2
=> y/x = 3/2
=> y : x = 3 : 2
So, the ratio of one berk and one pen is 3 : 2
