Now, In the first set, we see that there are 5 glasses, out of which 4 are small glasses and one is the normal one. In the second set, there are two glasses, one small and one normal. Assume the value of big glass is x and small glass is y. Now, x + 4y = 34

And x + y = 19 Solving the equation, we get 3y = 15 Or y = 5 Small glass = 5 Therefore, the value of the big glass is

x + 5 = 19 x= 19-5 x = 14 Big glass = 14
