Step-by-step explanation:
1.
no of sides = 360°/each exterior angle
=360°/72°
=5 sides
2.
Shriya =x
arjun =2x
5years ago(x-5 ) and his age is also3 times Shriya's age so 3(x-5)
and arjun age =(2x-5 )
so, =(2x-5)= 3(x-5)
=x=15-5
x=10
and 2x means arjun's age =2*10=20
3.
let no of rs 10 ,rs 50and rs 100with anil be 3 x,4x,5x respectively
value of 3x=rs 10 *3 x=rs 30 x
''. " 4x =rs50*4x =200x
". ". 5x =rs 100*5x =500x
total value of notes rs 200x+500x+30x=730x
but,. 730x=73000
=x=73000/730= 100
Hence ,no.of rs 10 notes with anil =3*100=300
". ". rs 50. ". ". ". =4x*100=400
". ". rs 100. ". ". =5x*100=500
