Answer 1

Answer:

here your answer.........

T=2(2/3) year's

Step-by-step explanation:

we know that

A = p(1 + TR/100 )

here

A = total money

p = principle money

T = time

R = rate of interest

according to question

p= 12600

R = 9%

A = 15624

find T = ?

put the values above identity

15624 = 12600[ 1 + ( T × 9 )/100 ]

15624/12600 = ( 100 + 9T )/100

15624/126 = 100 + 9T

124 = 100 + 9T

124 - 100 = 9T

24 = 9T

T = 24/9

T = 2(2/3) year's.
