A) 60
B) 65
C) 90
D) None of these
Correct Answer: A
Solution :
Let the number of guests be x. Then, number of bowls of rice \[=\frac{x}{2},\] number of bowls of dal \[=\frac{x}{3},\] number of bowls of meat \[=\frac{x}{4}.\] \[\therefore \] \[\frac{x}{2}+\frac{x}{3}+\frac{x}{4}=65\] \[\Leftrightarrow \] \[\frac{6x+4x+3x}{12}=65\] \[\Leftrightarrow \] \[13x=65\times 12\] \[\Leftrightarrow \] \[x=\left( \frac{65\times 12}{13} \right)=60.\]You need to login to perform this action.
