Answer 2

She pay back the money in 2 years.

Step-by-step explanation:

Principal = Rs.1200

Interest = Rs.120

Rate of interest = 5%

Formula : $SI = \frac{P \times T \times R}{100}\\120 =\frac{1200 \times 5 \times T}{100}\\120 \times 100 = 1200 \times 5 \times T\\\frac{120 \times 100}{ 1200 \times 5}=T\\2=T$

Hence she pay back the money in 2 years.
