12 cakes of soap together weigh 5 kg and 604 gm. Find the weight of (i) One cake in both kg and gramme (ii) 5 cakes in kg.
Answers:
Weight of 12 cakes of soap = 5 kg and
604 gm = 5 kg and (604/1000) kg
= 5.604 kg.
(i) Weight of 12 cakes = 5.604 kg
∴ Weight of 1 cakes = 5.604/12
= 0.467 kg
Weight in gm = 0.467 × 1000 = 467 gm
(ii) Weight of one cake = 0.467 kg
Weight of five cakes = 0.467 × 5 = 2.335 kg
