    Answer : Option E

    Explanation :

    Given : S.I. = Rs. 50.


              I gives, R = 10% p.a.


              II gives, T = 10 years.


     Sum =   \(\left(\frac{100 *S.I}{T*R}\right)\)   = Rs.     \((\frac { 100*50 } {10*10 } )\) = Rs. 50.


    Thus, I and II together give the answer.


     Correct answer is (E).
