Answer 1

Answer:

Step-by-step explanation:

Formula

S.I = principal * rate of interest *year/100

total amount = principal + S.I

total amount - S.I = P

S.I =Total amount - P

P * R *T/100 = total amount - P

Given

rate of interest = 12%

total amount = 13440

no. of years = 5

solution -

let P be x

S.I =Total amount - P

P * R *T/100 = total amount - P

x * 12 * 5 /100 = 13440 - x

3x /5 = 13440 - x

3x/5 +x = 13440

8x /5 = 13440

8x = 13440*5

x = 13440 * 5/ 8

x = 8400
