• D. $25$ and $25$

Answer 1

Answer: (D)

$25$ and $25$

Let number of Re.$1$ coin $=x$

Number of Re. $2$ coin $=y$

A/q,

$x+y=50$ ..............................(i)

$x+2y=75$ ..............................(ii)

On Solving eqn. (i) and (ii), we get

$x=25$ and $y=25$

Hence, D is the correct option.
