Question

Two pipes of length 1.5 m and 1.2m are to be cut into equal pieces without leaving extra length of pipes . The greatest length of the pipes of same size which can be cut from these two lengths will be :

• A. 0.13 m
• B. 0.4 m
• C. 0.3 m
• D. 0.41 m

Answer 1

Answer:

C. 0.3 m

The greatest length of the pipes of same size which can be cut from these two lengths = HCF(1.5, 1.2) = HCF( 15/10, 12/10) = HCF of numerator/ LCM of denominator = 3/10 = 0.3 metre
