Correct option is A)
The given three ropes are 7m, 12 m 95cm and 3m85cm long. We know that 1m=100cm, therefore,
The length of the respective ropes will be:
1st rope =7×100=700cm
2nd rope =(12×100)+95=1200+95=1295cm
3rd rope =(3×100)+85=300+85=385cm
Now, let us factorize the length of the ropes as follows:
700=2×2×5×5×7
1295=5×7×37
385=5×7×11
The highest common factor (HCF) is 5×7=35
Hence, the greatest possible length that can be used to measure these ropes is 35cm.
