Answer: (4) None of these
Explanation:-
Given-
Rate = 10 %, T = 4 & 5 years  Difference of the  S I = Rs.220
Let the principal is Rs.X.
Formula-
Simple Interest = P x R x T/100
Where, P = principal , R = rate, & T = time.
According to the question,
P x 10 x 5/100 – P x 10 x 4/100 = 220
P/2 – 2 P /5 = 220
(5 P – 4 P)/5 = 220
P = 220 x 5
P = Rs.1100
Hence, the principal is Rs.1100.
