Given in the question the equation:

3x² - 10x + k = 0

suppose 1st root of this equation is r

so as stated in the question, second root of this equation will be 1/r

Adding the roots gives = −b/a
Multiplying the roots gives = c/a
a b c

3x² - 10x + k = 0

r x 1 / r = c / a

r / r = k / 3

1 = k / 3

3 = k
