Answer 1

10x +50y=1900paise

x + y=70

x=70-y

10(70-y)+50y=1900

y=30

x=40

x is 10 paise coin and y is 50 paise coin.

Answer 2

Answer:

50 paise coin=30

10 paise coin=40

Step-by-step explanation:

x=10 paise y=50 paise

given x+y =70

and value 10x+ 50y =1900

19 rupees =1900 paise

x+y=70 ×10

10x+50y=1900

10x+10y=700

10x+50y=1900 subtract

-40y=-1200 y=30

40 +30=70
