Question

find the compund interest on rs 1200 for 2 yrs at 5per per annum​

Answer 1

Step-by-step explanation:

A=P(1+R/100)^T

A=1200(1+5/100)^2

A=1200(21/20)^2

A=1200×441/400

A=₹1323

Answer 2

Step-by-step explanation:

A=P(1+R/100). (raised to) N

A=1200 (1+5/100) 2

A=1200(1+1/20)

(by cross multiplication)

A=1200(20+1/20)

A=1200(21/20)

A=1200×21/20×21/20

(by division method)

A=1323₹

Let, compound interest = amount - principle

Compound interest = 1323 - 1200

Compound interest = 323
