statement 4

according to statement 1 interest rate per annum is given and for 1 year we can calculate the interest just by simple interest formula = p.1.r/100

So, statement 1 is alone sufficient.

According to statement 2 interest earned inn two years is Rs. 132

Applying the compound interest formula:

432 = 300 (1 + r)2

144/100 = (1+r)2

(1+r) = 1.2

From here we will get r = .2

So the rate is again 20%

Now, again we could calculate the interest for 1 year.

So, statement 2 is also alone sufficient.
