Answer:

LET the number of 50 RUPEE COIN be x.

and the number of 100 rupee coin be y.

Step-by-step explanation:

so,ACCORDING to the first condition

50x+100y=1500

x+2y=30----equation1.

again,x+y=13----equation2.

1-2=x+2y=30

x+y=13

(-)(-)=(-)

------------

y=17

now,1x17=x+2x17=30

=x+34=30

=x=30-34=4.
