Let x = 0.6666666..........
Now 10x = 6.66666.......,
Subtract both of them,
=> 9x = 6,
=> x = 6/9,
=> 0.666666666666666....... = 6/9 (Since x remains same)
Now, Let y = 0.47474747.........,
=> 100y = 47.474747.........,
Subtract them,
=> 99y = 47,
=> y = 47/99,
=> 0.47474747........ = 47/99.(Since x remains same),
Now the question is x+y = ?,
=> 6/9 + 47/99,
=> (66+47)/99,
=> 113/99,
Therefore the answer is (c) 113/99,
Hope you understand, Have a Great Day ! Merry Christmas !
