Answer:

16.6%

Step-by-step explanation:

Let P = 100

A = 300

 \frac{100 \times r \times 12}{100}  = 200

r =  \frac{200}{12}  =  \frac{50}{3} \% = 16.6\%

first take out the principal be let it rs.100 and amount be thrice of principal i-e 3×100=300 and then take out the SI by subtracting Amount and Principal, after taking out SI, Let Time=SI×100/P×T and take out time by cancelling and fraction will convert into mixed fraction
