• A.
  1 : 1
• B.
  2 : 1
• C.
  1.5 : 1
• D.
  2.5 : 1

Answer 1

The correct option is C

1.5 : 1
Ratio of male to female in 2011 is given in graph.

Let there will be 100 males and 100 females in 2011.

Now number of females in 2011 is same as number of females in 2012 as given in question.

So, female in 2012 is also 100.

Ratio of male to female in 2012 is 1.5 given in graph

$\frac{M}{F}=1.5$

$M=150\because (F=100in2012)$

So there are 150 males in 2012.

Ratio of male in 2012 to male in 2011

$=\frac{150}{100}=\frac{1.5}{1}$
