| The number of boys in a class is three times the number of girls. |
| Which one of the following numbers cannot represent the total number of children in the class? |
A) 48
B) 44
C) 42
D) 40
Correct Answer: C
Solution :
Number of boys in class = x Number of girls in class = 3x Total number of children = x+ 3= 4x From option, [a] \[4x=48\Rightarrow \,\,\,x=12...(a)\] [b] \[4x=44\Rightarrow \,\,\,x=11...(b)\] [c] \[4x=42\Rightarrow \,\,\,x=10.5...(c)\] [d] \[4x=40\Rightarrow \,\,\,x=10...(d)\] Hence option [c].
