Answer: (1) Rs.2100
Explanation:-
Given-
Principal = Rs.21,00,   Amount = Rs.2,352   and    time = 2 years
Then, Simple Interest = 2352 – 2100  = Rs.252
252 = 2100 x 2 x R/100                     Here, R = rate.
252 = 42R
R = 252/42
R = 6%
Rate is decreases by 1%
Then, Rate = 6 – 1 = 5%
New simple interest = 2100 x 2 x 5/100
= 21 x 10 = 210
hence, the answer is (1) Rs.2100.
