what is X's present age in years?
a)35
b)42
c)Cannot be determined
d)None of these

Hello :) This sum should take you no more than 5 seconds if you see the Magic with the numbers ;)
The ratio increases from 5:6 to 6:7 .. means one on each side... In this case, how much time is past gives us the answer.
See, after 7 years, ratio increases from 5:6 to 6:7, means each 1 part of the ratio is 7 years itself! :)
Hence X's age is 6 X 7 = 42 :)
I hope you Understood :) Leave me a comment otherwise! ;)

Hey :) The Answer is 5 X 7 = 35 :)
My bad :) 42 is X's age 7 years from now :)
Answer is (a) 35 :)
