Answer:
B=110,X=230
Explanation:
Acc. To dobereiner's traids,
The atomic mass of middle element is the average of the other.
So atomic mass of C is
At.mass ofA+At.mass ofB
------------------------------------------
2
=100+120/2
=110
Similarly atomic mass of X is(y)
250+y
------------- = 240
2
=> 250+y=480
=> y=480-250
=> y=230
