Question

A packet of crisp weighs 32 grams to the nearest gram. a multi-pack crisp contains 10 packets. work out the least and the greatest weighs of the multipack. ignore the weight of the multipack

Answer 1

Least weight of multipack :

31.5 * 10 = 315g

Highest weight of multipack :

32.4 * 10 = 324g

Explanation:

Weight of a packet of crisp to the nearest gram = 32 g

The least value of the weight of actual packet = 31.5 (least number which can give 32 when rounded to the nearest gram)

The highest value of the weight of actual packet = 32.4g (Highest number which can give 32 when rounded to the nearest gram)

Since a multipack contains 10 packets of crisp :

Least weight of multipack :

31.5 * 10 = 315g

Highest weight of multipack :

32.4 * 10 = 324g
