A) 7
B) 4.5
C) 3.2
D) 2.5
Correct Answer: A
Solution :
\[8-\left[ 7-\left\{ x-\left( 4-\frac{7}{7} \right) \right\} \right]=5\] \[\Rightarrow \] \[8-[7-(x-3)]=5\] \[\Rightarrow \] \[8-[7-x+3]=5\] \[\Rightarrow \] \[8-10+x=5\] \[\Rightarrow \] \[-\,2+x=5\] \[\Rightarrow \] \[x=7\]You need to login to perform this action.
