    1. 3
    2. 1
      3
    3. - 3
    4. None of these
Correct Option: A

The given quadratic equation is 3x2 - 10x + 3 = 0
Comparing with ax2 + bx + c = 0, we get
a = 3, b = −10, c = 3

∴ Sum of the roots ( k1 + k2 ) = -
a
=
10
b
3
∵ One root k1 =
1
3
∴ The other root k2 =
10
-
1
=
9
= 3.
3
3
3

Therefore , The other root is 3 .
