Answer:
1, the method is wrong. Read below.
Step-by-step explanation:
A sweetseller has 420 kaju barfis and 130 badam barfis.
She wants to stack them in such a way that each stack has the same number, and they take up the least area of the tray. What is the number of that can be placed in each stack for this purpose?
1. Each stack should have the same number.
The number can be the common factors of 420 and 130.
Reason : Common factors of 420 and 130 divides without remainder, so each stack will have the same amount.
2. They take up the least area.
The number should be the lowest(important) from the above.
From 1 and 2, we know that we have to find 'LCF' to solve the problem.
So finding HCF is not a correct method.
'LCF' is 1.
Conclusion
1 is the answer and the method is not correct.
The question is wrong.
