Answer :
Step-by-step explanation:
Cost of 50g of chocolate= 45 p
cost of 1 g of chocolate = 45/50 p. = 0.9p
cost of 1kg = 1000g = 0.9* 1000 p
= 900 p
1kg = 1000g
1000/50 = 20
So 1kg of chocolate equals 20 lots of 50g chocolate
One 50g chocolate is 45p
45p*20=900p
1kg would cost 900p
1000/50 = 20
So 1kg of chocolate equals 20 lots of 50g chocolate
One 50g chocolate is 45p
45p*20=900p
1kg would cost 900p
