AFCAT Model Paper 4

Given:
If number of child half then number of notebooks have each child = 16
Formula used:
If a : b :: c : d
then a × d = b × c
Calculation:
Let the number of children of the class be x
Then, number of notebooks each child will get =

x

8

If the number of children were

x

2

Number of notebooks each child will get = 16
Now, According to the question
Total number of notebook is constant
So, (

x

2

)×16=x×(

x

8

)
⇒ x = 64
So, total number of notebooks = 64 × 8
⇒ 512
∴ Total number of notebooks were distributed is 512.
