$\huge{ \bf{ \underline{ \red{Given}}}}$

A money box contain one rupee and 2 rupees in ratio 5:6.

Total money is ₹85

Find :- Number of rupee coins??

Solution:-

${ \sf{ \implies{ The \: ratio \: of \: one \: rupee \: and \: two \: rupee \: is \: 5:6}}}$

${ \sf{ \implies{Value \: of \: one \: rupee \: coin \: = 1 \times 5x = 5x}}}$

${ \sf{ \implies{Value \: of \: two \: rupee \: coins \: = 2 \times 6x = 12x}}}$

${ \implies{ \sf{5x + 12x = 85}}}$

${ \implies{ \sf{17x = 85}}}$

${ \implies{ \sf{x = \frac{85}{17} }}}$

${ \implies{ \sf{x = 5}}}$

The number of two rupees in box = 5×6=30

${ \therefore{ \sf{There \: are \: 30 \: two \: rupee \: coins}}}$
