Question

Joyti and vandana took a loan of equal amount at the same rate of interest.joyti cleared her loan after 2 years by paying Rs. 8680. vandana also cleared her loan after 5 years by paying an amount Rs. 11200. find the amount of loan of each

Answer 1

jyoti;-
I=PTR/100
8680=X*2*Y/100
XY=434000-1 EQUATION
VANDANA:-
11200=X*5*Y/100
XY=224000-2 EQUATION
HERE X=224000/Y
SUBSTITUTING THIS IN THE FIRST EQUATION,
WE GET Y=1.9375
AGAIN SUBSTITUTING Y IN SECOND EQUATION WE GET
X=115612.9032258065
SO THEY SAID BOTH JYOTI AND VANDANA TOOK SAME AMOUNT AS LOAN.
SO X VALUE IS THE ANSWER
