let the number of 50p coins be 5x
number of 25p coins become 9x
number of 10p coins become 4x
total amount=206*100=20600
(5x)*50 + (9x)*25 + (10x)*4 = 20600
on solving
x=40
Hence number of 50p coins is 5x= 200 nos
number of 25p coins become 9x
number of 10p coins become 4x
total amount=206*100=20600
(5x)*50 + (9x)*25 + (10x)*4 = 20600
on solving
x=40
Hence number of 50p coins is 5x= 200 nos
