A) 10
B) 12
C) 15
D) 20
Correct Answer: B
Solution :
Let the given number be x. Then, \[\left( x\times \frac{3}{2} \right)-\left( x\div \frac{3}{2} \right)=10\] \[\Rightarrow \] \[\frac{3}{2}x-\frac{2}{3}x=10\] \[\Rightarrow \] \[\frac{9x-4x}{6}=10\] \[\Rightarrow \] \[5x=60\] \[\Rightarrow \] \[x=12\]You need to login to perform this action.
