Simple & Compound Interest in 10 min | SI–CI Formula + Shortcuts |

Описание: Is video mein hum Simple Interest (SI) aur Compound Interest (CI) ko ek hi class mein complete karenge – formulas, concept, aur superfast tricks ke saath. Video specially design kiya gaya hai SSC, RRB, Bank PO, IBPS, SBI, Railway, CDS, NDA jaise competitive exams ke liye.

📘 Concepts Covered (Step by Step):

1️⃣ Simple Interest (SI):
Formula:
SI = P ⋅ R ⋅ T / 100

Yahan P = Principal (amount invested), R = Rate (% per annum), T = Time (years).

2️⃣ Compound Interest (CI):
Formula (annual compounding):
CI = P (1+R/100)^T − P
Ya Amount:
A = P (1+R/100)^T
CI = A − P

Super Trick – CI – SI for 2 Years:
Jab time = 2 years ho, to difference between CI and SI directly nikal sakte hain:
Difference
= P⋅(R/100)^2
