It is given that

Maturity values = Rs. 30975

Monthly installment = Rs. 2500

Rate of interest =6%

Let the time be x months

∴ Qualifying amount = 2500×(x+x+1)

____________

=1250 ( x^2+x)

Now, S.I. = 1250 (x^2+x)×6

_____________

100 × 12

= 25/4 ( x^2+x)

Principal = Rs. 2500 × x

= 2500x +25/4 (x^2+x)=30975

=10000x + 25x^2+25x =123900

=25x^2+10025x - 123900= 0

=25 ( x^2 + 401x- 4956 ) =0

now

x^2+401x - 4956 =0

mark as branliest answer
