A) 200
B) 250
C) 100
D) 150
Correct Answer: C
Solution :
Let the number be x and y. |
According to the question, |
\[\therefore \] \[x+y=45\] ...(i) |
Again, \[x-y=\frac{1}{9}(x+y)\] |
\[\Rightarrow \] \[x-y=\frac{1}{9}\times 45\]\[\Rightarrow \]\[x-y=5\] ?(ii) |
On adding Eqs. (i) and (ii), we have |
\[\begin{align} & x+y=45 \\ & \frac{x-y=5}{2x=50} \\ \end{align}\] |
\[\Rightarrow \] \[x=25\] |
\[\therefore \] \[y=45-25=20\] |
Now, LCM of 25 and 20 = 100 |
