C) 23
D) 24
Correct Answer: C
Solution :
Let the numbers be \[x,\] \[x+1,\] \[x+2,\] \[x+3,\,\] \[x+4,\] \[x+4,\]and \[x+6.\] Then \[\Rightarrow \frac{\begin{align} & x+\left( x+1 \right)+\left( x+2 \right)\left( x+3 \right) \\ & \,\,\,+\left( x+4 \right)+\left( x+5 \right)+\left( x+6 \right) \\ \end{align}}{7}=20\] \[7x+21=140\Rightarrow 7x=119\] \[\therefore \]Largest number\[=x+6=23\]You need to login to perform this action.
