A) 23
B) 24
C) 25
D) 26
Correct Answer: B
Solution :
[b] Let the number be \[10x+y.\] Then, according to the questions, |
\[y=2x\] ...(i) |
and \[(x+y)-2=(10x+y)\times \frac{1}{6}\] |
\[\Rightarrow \] \[(x+2x)-2=(10x+2x)\times \frac{1}{6}\] |
\[\Rightarrow \] \[3x-2=12x\times \frac{1}{6}\] |
\[\Rightarrow \] \[3x-2=2x\]\[\Rightarrow \]\[3x-2x=2\] |
\[\therefore \] \[x=2\] and \[y=4\] |
Then, required number |
\[=10\times 2+4=20+4=24\] |
