240T=1680*15*T/100+15T
240T=25200T/100+15T
24000T+3600T2=25200T
T(24000+3600T)=25200T
24000+3600T=25200
3600T=25200-24000
T=1200/3600
T=1/3
T=4 Months
240T=25200T/100+15T
24000T+3600T2=25200T
T(24000+3600T)=25200T
24000+3600T=25200
3600T=25200-24000
T=1200/3600
T=1/3
T=4 Months

B.D= 1600*15*T/100=240T
T.D=1680*15*T/100+15T
NOW,B.D=T.D
THUS T=1/3*12=4 MONTHS
T.D=1680*15*T/100+15T
NOW,B.D=T.D
THUS T=1/3*12=4 MONTHS
