Answer 2

GIVEN,

amount= 8280, rate= 7% p.a. time =6 months.

TO FIND,

the principal,

SOLUTION,

let the principal be P,

time= 6 month = 0.5 years.

we are given that the amount= 8280,

we know that,

AMOUNT= PRINCIPAL + INTEREST.

let us now calculate the rate of interest,

$SI=\frac{P*R*T}{100}$

substituting the values,

$SI=\frac{P*7*0.5}{100} \\\\SI= 0.035 P$

now using equation 1,

AMOUNT= P+ 0.035P

now according to the problem,

8280= 1.035P

∴P= ₹8000

HENCE THE SUM FOR WHICH THE AMOUNT WILL BE ₹8280 IS ₹8000,
