​

Answer 1

Answer:

The number of 5 rupee coins are 50

and the number of 10 rupee coins are 50.

Step-by-step explanation:

Let the number of 5 rupee coins be x

Let the number of 10 rupee coins be 100-x

Now 5x+10(100-x)=750

5x+1000-10x=750

-5x=-1000+750

-5x=-250

5x=250

x=250/5

x=50

So the number of 5 rupee coins are 50

The number of 10 rupee coins are 100-x

=100-50=50

VERIFICATION

5(50)+10(50)

250+500

=750
