Free notebooks were distributed equally among children of a class. The number of notebooks each child got was one-eighth of the number of children. Had the number of children been half, each child would have got 16 notebooks. Total how many notebooks were distributed?
A 256
B 432
C 512
D 640
Solution
Correct Answer: Option C
Let total number of children be x.
Then, x x (1/8)x = x/2 x 16
=>x = 64.
So, Number of notebooks = (1/8)x2
= ((1/8) x 64 x 64) = 512.
