Answer 1

$\texttt{Total\:amount\:in\:the\:bag\:=Rs.\:750} \\ \texttt{Let\:the\:ratios\:be\:5x\:8x\:and\:4x} \\ \\ \textbf{According\:to\:question,} \\ \\ \begin{gathered} \: (5 \times 1) + (8 \times 0.5) + (4 \times 0.25) = 750 \\ 5x + 4x + x = 750 \\ 10x = 750 \\ \: x = \frac{750}{10} \\ \: x = 75\end{gathered} \\ \\ \text{Thus,} \\ \boxed {\begin{array}{c}5x = 5 \times 75 = 375 \\ 8x = 8 \times 75 = 600 \\ 4x = 4\times 75 = 300\end{array} }\\ \\ \textrm{No.\:of\:coins\:in\:Rupee\:=\:375} \\ \textrm{No.\:of\:coins\:in\:50\:paisa\:=\:600} \\ \textrm{No.\:of\:coins\:in\:25\:paisa\:=\:300}$
