The greatest length of the scale that can measure exactly 20 cm, 90 cm, 1 m 25 cm and 1 m 30 cm length is:

5 cm

15 cm

20 cm

30 cm

✅ Correct Option: 1

Convert all lengths to cm: 20, 90, 125, 130. The greatest length of scale = HCF of these. $20 = 2^2 \times 5$ , $90 = 2 \times 3^2 \times 5$ , $125 = 5^3$ , $130 = 2 \times 5 \times 13$ . HCF $= 5$ cm.
