Answer 2

Given thαt,

• Compound Interest (C.I) = ₹ 500
• Amount (A) = ₹ 700

◾We need to find the principle(P).

______________________________

Solution :

We αlreαdy know thαt,

$\large\star{\sf{\pink{ Amount (A) = Principle(P) + Compound\: Interest(C.I.)}}}$

• Substituting the vαlues in the formulαe.

$\longrightarrow{\sf{ 700 = P + 500}}$

• Trαnsposing 500 to L.H.S.

$\longrightarrow{\sf{ 700-500 = P}}$

$\large\star{\boxed{\sf{\pink{P = 200}}}}$

Hence, the principle is ₹ 200.
