Question

    If 1/(x+ 1/(y+ 1/z)) = 13/30, then find x+y+z=

    ?
    A 19 Correct Answer Incorrect Answer
    B 8 Correct Answer Incorrect Answer
    C 9 Correct Answer Incorrect Answer
    D 13/4 Correct Answer Incorrect Answer

    Solution

    Dividing numerator and denominator of RHS by 13. ⇒ (13/13)/(30/13) = 1/(30/13) = 1/(2+ 4/13) Again dividing by 4. ⇒ 1/(2+ (4/4)/(13/4)) = 1/(2+ 1/(13/4)) ⇒ 1/(2+ 1/(3+ 1/4)) ∴ x = 2, y = 3, z = 4 ∴ x+y+z= 9
