Question 2409
 
 Your problem does not say whether the interest is to be calculated on "Simple Interest System" or "Compound Interest System".  Let us solve this problem on simple interest system. Under S.I., the formula is as below:
 
         I = {{{P*n*r/100}}} ;   P=Principal amount; n=term(no.of years); 
                                 r=rate of interest; I=Interest amount.
When 3 values have been given, we can easily find out the other.

Here,    Interest = {{{(35000*8*7)/100}}} = 19,600

The total amount = P + I = 35,000 + 19,600  =  54,600.      Answer
