Question

find the principal when R=5%,T=2years I=50 ruppes​

Answer 1

Rate = 5%

Time = 2 years

Interest = Rs. 50

We know,

$\bf{}I = \frac{P \times R \times T}{100} \\ \\ \sf{}50 = \frac{P \times 5 \times 2}{100} \\ \\ \sf{}P = \frac{50 \times 100}{5 \times 2} \\ \\ \sf{}P = \frac{50 \times 10\cancel0}{1 \cancel0} \\ \\ \sf{}P = 500$

Thus,

• Principal is Rs. 500

Answer 2

1. Interest=50
2. Rate=5%
3. Time =2years
4. principal =?

solve÷Interest=p×t×r÷100

=50=p×2×5÷100

P=50(2×5÷100)

p=50(10÷100)

p=50(10)

p=50×10=500
