A=4200

Simple Intrest=340

to find =P=?

A= P +SI

4200=P+340

P=4200 -340

hence P =3860

Answer 2

If the amount is Rs 4200 and Simple interest is Rs. 340, The principal is Rs. 3860.

Step-by-step explanation:

The principal is the initial burrowed amount on which interest is applied.

To calculate the principal we use the formula:

$Amount = Principal+Simple\ Interest$

Given:

Amount = Rs. 4200

Simple Interest = Rs. 340

Substituting in the formula:  

$4200 = Principal + 340\\Principal = 4200 - 340\\Principal = 3860$

The Principal = Rs. 3860.
