Four pieces of wooden sticks A,B,C and D are placed along the length of 30 cm long scale as shown in Fig. 10.4.
Which one of them is 3.4 cm in length?
(a) A
(b) B
(c) C
(d) D
We can observe from the given figure, that stick C lies between 10.4 cm and 7 cm. So, its length is (10.4 – 7) cm = 3.4 cm.
Hence option (C) is correct.
