Question

4. What is the principal, if the interest is Rs35 for 1 year at 7p.c.p.a? ​

Answer 1

INTEREST=P×N×R/35

35=P×1×7/100

35×100/7=P

5×100=P

500=P

Answer 2

Answer:

The principal amount is Rs.500

Step-by-step explanation:

As per the data given in the above question,

It is given that Interest is Rs.35

Time period of 1 year,

Rate of Interest is 7%

We have to find the principal amount,

Here we have to use the formula of $SI=\frac{PRT}{100}$

We can write it as,

$\frac{PRT}{100}=I \\PRT=I\times 100\\P=\frac{I\times 100}{RT}$

Substitute the value in above equation we get,

$P=\frac{35\times 100}{7\times 1}\\P=\frac{3500}{7}$

Now 35 is divided by 7 we get 5 remaining zero is added we get 500,

$P=Rs.500$

The principal amount is Rs.500
