Correct Answer - Option 2 : x = 8 and y = 6
(1235)x = (3033)y
Converting both the RHS and LHS into its decimal equivalent, we get:
(x3 + 2x2 + 3x + 5)10 = (3y3 + 0y2 + 3y + 3)10
Substituting the values given in the options in above equation, we get:
x = 8 and y = 6
Proof:
Putting x = 8 in x3 + 2x2 + 3x + 5
= (8)3 + 2(8)2 + 3(8) + 5
= (699)10
Putting y = 6 in 3y3 + 0y2 + 3y + 3
= 3(6)3 + 3(6) + 3
= 3(216) + 18 + 3
= (699)10
