We know that when m is a odd number ( xm + am ) is divisible by ( x + a ).
? Each one is divisible by (41 + 43).
So Common factor = (41 + 43).
U ? A = {a, b, c, d, e, f} ? {a, b, c} = {a, b, c, d, e, f} = U
(U ? A)? = ?.
Sunil's income is less than Mukul's = [(10 / (100 + 10)] × 100 %
= ( 1000 / 110 )%
= 9.09 %
So, 39 is wrong.
So, 33 is wrong. It must be 35
∴ x = 7.
So, 40 is wrong.

Common factor means a number which divides Then why not this is 2 (, 43-41), because 2 is also a common factor of the given
