It is EASY .

From the two sequence you get that 4 times X is 100, X = 25 and from X(25) = 5 x Y, Y = 5. X(25) + Y(5) = 30 .

Lets assume Y=10. It wouldn't work because X would equal 16.6666666..... . If Y= 5 X=25. 25 + 5 = 30.

Why would Y=5, X=25? It does not make any sense.

Also, what does X 3 X3 means? Does it mean 3 X 3X ?
