a certain amount of money amount to Rs.5500 in 2 years and to Rs.5750 in three years. Find the principal and the rate of interest​

Answer 1

Answer:

Step-by-step explanation:

PARAMETERS GIVEN,

FOR TIME ( 2 YEARS),

AMOUNT = ₹5500

FOR TIME ( 3 YEARS)

AMOUNT = ₹5750

SO,

FOR TIME( 2 YEARS),

A=P(1+R/100)ⁿ

5500=P(1+R/100)²

5500/P = [(100+R)/100]²

(5500*100*100)/P = (100+R)²

55000000/P = (100+R)²

FOR TIME(3 YEARS),

A=P(1+R/100)³

5750=P(1+R/100)³

5750/P=[(100+R)/100]³

(5750*100*100*100)/P = (100+R)³

SO,

A.T.Q.,

55000000/P =
