Answer:

THE SUM IS OF ₹625

Step-by-step explanation:

PARAMETERS GIVEN:-

CI - SI = ₹1

TIME = 2yrs

RATE% = 4%

SO,

LET THE SUM BE x

SO,

FOR CI:-

CI = {P(1+R/100)ⁿ - P}

    = {x(1+4/100)² - x}

    = 676x/625 - x

    = (676x - 625x)/625

    = 51x/625

FOR SI:-

SI = PRT/100

   = (x*4*2)/100

   = 2x/25

NOW,

A.T.Q.,

CI - SI = ₹1

(51x/625) - (2x/25) = ₹1

(51x - 50x)/625 = ₹1

x/625 = 1

x = ₹625

SO,

THE SUM IS OF ₹625
