Answer: (2) Rs.2,200
Explanation:-
 Given-
Principal = ?, Amount = Rs.7,200 , time = 4 years, rate = 11 %
Formula-
Simple Interest = P x R x T/100
Where, P – principal, R – rate  & T – time.
S I = P x 11 x 4/100
S I = P 11/25
7200 = P + 11 P/25
7200 = (25 P + 11 P)/25
7200 x 25 = 36 P
P = 200 x 25
P = 5000
Then, S I 72,00 – 5000
= Rs.2,200
Hence, the answer is (2) Rs.2,200
