    Answer: (B) 102

    Solution:-
    If Rs.85 amounts to Rs.95 in 3 years.
    Interest = 95 – 85
    = Rs.10
    Time = 3 years & Rate of Interest = ?

    Then, 10 = 85 x 3 x ?/100
    10 = 51 x ?/20
    ? = 200/51
    So, Rate of Interest = 200/51

    Now, Principal = Rs.102, Time = 5 years & Rate of Interest = 200/51
    Then, Simple Interest = 102 x 5 x 200/51 x 100
    = 2 x 5 x 2
    = Rs.20

    Thus, Amount = 102 + 20
    = Rs.122

    Hence, the correct answer is option (B) 122.
