RATE OF INTREST IS 5 , INTREST IS 6000 and TOTAL AMOUNT IS 18000 FIND THE PRINCIPAL AND ALSO FIND NUMBER OF YEAR?​

Answer 1

Answer:

principal is 12000 and year is 10

Step-by-step explanation:

Rate of intrest = R =5

Simple intrest = SI = 6000

Amount = A = 18000

Principal = P = ?

Year = N = ?

soln:-

A = P + SI

18000 = P + 6000

18000 - 6000 = P

12000 = P

Now

SI = P +R + N

_______

100

6000 = 12000 + 5 + N

___________

100

6000 = 12000 + N

_________

20

6000 = 600 + N

6000

_____ = N

600

10= N

Therefore PRINCIPAL IS 12000 AND YEAR IS 10
