A piece of ribbon folded five times is placed along a 30 cm long measuring scale as shown in Fig. 10.2.
The length of the ribbon is between
(a) 1.15 m - 1.25 m
(b) 1.25 m - 1.35 m
(c) 1.50 m - 1.60 m
(d) 1.60 m - 1.70 m
According to the above figure, the five times folded ribbon piece is
(27.5 – 2) cm × 5 = 1.275 m long approximately.
Hence option (B) is correct.
