Question

A piece of ribbon folded five times is placed along the 30 cm long measuring scale from 2cm to 27.5 cm. The length of the ribbon is between

• A. 1.15 - 1.25 m
• B. 1.25 - 1.35 m
• C. 1.50 - 1.60 m
• D. 1.60 - 1.70 m

Answer 1

The correct option is B 1.25 - 1.35 m

Since, ribbon is folded 5 times,
Length of ribbon

= (27.5 – 2) cm x 5

= (25.5 x 5) cm

= 127.5 cm

= 1.27 m

1.27 m lies in the range of 1.25 m – 1.35 m.
