Question

The length of a chain is given as 16900 cm correct to the nearest 100 cm. What is the lower bound for the length of the chain?

Answer 1

Answer: 16850 cm

Explanation:

Since the length of a chain is given as 16900 cm correct to the nearest 100 cm

Length = (16900 +/- 50)cm

The lower bound = 16900 - 50

The lower bound = 16850 cm

While

The upper bound = 16900 + 50

= 16950 cm
