(P x T x 0.08)+ P = 765 i.e P ( 1+ T x 0.08) = 765 - Eq 1 (640 x T x 0.05) + 640 = 750 - Eq 2 From Eq 2 T = 3.4375 months Substituting T in Eq 1 P ( 1+ T x 0.08) = 765 P ( 1+ 3.4375 x 0 .08) = 765 P(1 +0 .275) = 765 P = 600 Sriram Somayajula

(P x T x 0.08)+ P = 765 i.e P ( 1+ T x 0.08) = 765 - Eq 1 (640 x T x 0.05) + 640 = 750 - Eq 2 From Eq 2 T = 3.4375 months Substituting T in Eq 1 P ( 1+ T x 0.08) = 765 P ( 1+ 3.4375 x 0 .08) = 765 P(1 +0 .275) = 765 P = 600

Thank you Pranav Sarma
