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.
