Solution

$Let P be the sum borrowed . Rate, R = 12 % p . a . Time, T = 2 yrs 4 months = 2 \frac{4}{12} yrs = \frac{7}{3} yrs Interest, I = Rs 168 \Rightarrow \frac{PRT}{100} = 168 \Rightarrow \frac{P \times 12 \times 7}{100 \times 3} = 168 \Rightarrow 7 P = 168 \times 25 \Rightarrow P = 600 So, required sum = Rs 600$
