Answers
3 brands A, B and C of biscuits are available in packets of 12, 15 and 21 biscuits respectively then minimum number of packets are LCM of 12 , 15 and 21. LCM of 12, 15 and 21 by division method is 420.
Taking the LCM for the 3 brands A, B and C of biscuits then the answer is 420. The shopkeeper must buy 420 packets minimum.
Answer: There are 420 number of packets of each brand he should buy.
Step-by-step explanation:
Since we have given that
Number of biscuits in brand A = 12
Number of biscuits in Brand B = 15
Number of biscuits in Brand C = 21
According to question, we have that if a shopkeepeer wants to buy an equal number of biscuits, of each brand.
We need to find the the minimum number of packets of each brand he should buy.
For minimum number of packets, we would L.C.M. of 12, 15, and 21.
As we know that L.C.M. of 12, 15, 21 = 420.
Hence, there are 420 number of packets of each brand he should buy.
