Answer:
➡️⏩➡️⏩➡️⏩➡️⏩➡️⏩➡️⏩➡️
given that
S.I = 1️⃣2️⃣0️⃣0️⃣
T = 3️⃣ years
so,
by using the formula
S.I = PRT/1️⃣0️⃣0️⃣
P = S.I × 1️⃣0️⃣0️⃣/RT
P = 1️⃣2️⃣0️⃣0️⃣×1️⃣0️⃣0️⃣
--------------------------------------
5️⃣× 3️⃣
P = 8️⃣0️⃣0️⃣0️⃣0️⃣
now,
C.I= P{(1️⃣➕R/1️⃣0️⃣0️⃣)^n ➖1️⃣}
C.I ={2️⃣1️⃣}^3 ➖8️⃣0️⃣0️⃣0️⃣
C.I = 9️⃣2️⃣6️⃣1️⃣➖8️⃣0️⃣0️⃣0️⃣
C.I= 1️⃣2️⃣6️⃣1️⃣. RS
