Question

10. Two bags of wheat contain 42 kg and 56 kg of wheat,
respectively. What is the greatest weight that can
be used to measure the wheat in each bag an exact
number of times? How many times will it take to
weigh all the wheat in the two bags using this weight?​

Answer 1

you have to find the HCF in this.

in questions like this you usually find the LCM but if we find the LCM in this question the question cannot be done

HCF of 42 and 56=14

for the 42 kg bag take 3 whole of the 14 kg bag

for the 56 kg bag take 4 whole of the 14 kg bag
