A) 1411 and 1079
B) 1412 and 1080
C) 1141 and 1709
D) 1214 and 1800
Correct Answer: A
Solution :
Ans. Let the tow numbers are \[x\] and \[y\]. Then, \[x+y=2490\]and 6.5% of \[x=8.5%\] of y \[\Rightarrow \] \[6.5x=8.5y\] \[\Rightarrow \]\[13x=17y\] \[\Rightarrow \]\[x=\frac{17}{13}y\] On putting this value in Eq. (i), we get \[\frac{17}{13}y+y=2490\] \[\frac{30}{13}y=2490\] \[\Rightarrow \] \[y=2490\times \frac{13}{30}=1079\] \[\therefore \] \[x=\frac{17}{13}y=\frac{17}{3}\times 1079=1411\]
