Answer 2

P=₹166.67

Step-by-step explanation:

Here, Simple interest = ₹55

Time = 9 months

Rate = 11/3

Now,simple interest = P×T×R/100

$55 = p \times 9 \times \frac{11}{3} \times \frac{1}{100}$

$55 \times \frac{1}{9} \times \frac{3}{11} \times 100 = p$

P = 500/3

P = ₹166.666

So,P = ₹166.67

Hence,the principal amount is ₹166.67
