• The number if two rupees is twice than the numberof 5 rupees.

To find:-

• The number of coins of 5 rupees and 2 rupees.

Solution:-

• Let the number of 5 rupees coin be x
• Then the number of 2 rupees coin will be 2x.

↝5×x +2(2x) = Rs.108

↝5x +4x =108

↝9x=108

$↝x = \frac{108}{9}$

↝x= 12.

• Therefore the number of 5 rupees coin is 12.

So the number of 2rupees coin will be = 2×12=24 .

$\boxed{ \mathfrak{ \blue{number \: of \: 5 \: rupees \: coin = 12}}}$

$\boxed{ \mathfrak{ \blue{number \: of \: 2\: rupees \: coin = 24}}}$

Verification:-

• 5 rupees = 5× 12=60
• 2 rupees =2×24=48
