Given:

Principal (P) = 8000 rupees
Total interest (I) = 6000 rupess

Now, Principal (P) = Total Amount − I= 18000 − 6000

= 12000 rupees​

Rate of interest (R) = 5%

Time (T) = `("I"xx100)/("P"xx"R")`= `(6000xx100)/(12000xx5)`

= 10 years

Total interest (I) = 2400 rupessRate of interest (R) = `2 1/2%`= `5/2%`

Time (T) = 5 years

Principal (P) = `("I"xx100)/("R"xx"T")`= `(2400xx100xx2)/(5xx5)`

Total Amount = P + I= 19200 + 2400

= 21600 rupees
