Answer 2

Answer:

If Principal = ₹ 8000, Rate= 10%, Interest= ₹ 4000, then period T = 5 years.

Step-by-step explanation:

Given:

Principal (p) = ₹ 8000,

Rate (r) = 10%,

Interest (I) = ₹ 4000,

Find: period T = ?

Interest

$(I)=\frac{PRT}{100} \\4000 =\frac{8000 \times 10 \times T}{100}\\ 8000 \times 10 \times T = 4000 \times 100\\80000 T = 400000\\T = 400000 \div 80000\\T= 5 years$

So, time (T) is 5 years.
