A) 50p coins = 400 20p coins = 600 10p coins = 800 B) 50p coins = 300 20p coins = 700 10p coins = 200 C) 50p coins = 800 20p coins = 400 10p coins = 200 D) 50p coins = 400 20p coins = 500 10p coins = 300 E) 60p coins = 500 20p coins = 400 10p coins = 300
50*2k + 20*3k + 10*4k = 40000   200k = 40000 =&gt; k = 200   50p coins = 2k = 2*200=
