1. 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 ?

2.  A. 256 B. 43 C. 512 D. 640 E. None of these

Then, x x$$\frac { 1 } {8 } X$$=$$\frac { X } { 2 }$$x 16     x = 64.
Number of notebooks =$$\frac { 1 } {8 } X$$2
=$$[\frac { 1 } {8 }$$x 64 x 64]=512
