Question

18 blue chairs and 27 red chairs have to be arranged in rows in such a way that there are an equal number of chairs of the same colour in each row. What is the maximum number of chairs that can be arranged in each row and how many rows can the chairs be arranged in?​

Answer 1

Answer:

highest number of chairs in each row is 9

Total rows is 5

Step-by-step explanation:

Find the Highest Common Factor of 18 and 27

The HCF of 18, 27 is 9

Thus the maximum no of chairs that can be arrranged in each row is 9

Total rows is (18+27)/9 = 5

Answer 2

Answer:3 chairs can be arranged in each row so that the same number of chairs are arranged

Step-by-step explanation:

Number of chairs in room A = 12

Number of chairs in room B = 18

Number of chairs in room C = 24

Now, we need to find the greatest possible no of chairs in each row in the 3 rooms.

This can be find out by finding the H.C.F. of all the number of chairs in three rooms

The required greatest number of chair = H.C.F.(12, 18, 24)

= 3

So, 3 chairs can be arranged in each row so that the same number of chairs are arranged

Step-by-step explanation:3 chairs can be arranged in each row so that the same number of chairs are arranged

Step-by-step explanation:

Number of chairs in room A = 12

Number of chairs in room B = 18

Number of chairs in room C = 24

Now, we need to find the greatest possible no of chairs in each row in the 3 rooms.

This can be find out by finding the H.C.F. of all the number of chairs in three rooms

The required greatest number of chair = H.C.F.(12, 18, 24)

= 3

So, 3 chairs can be arranged in each row so that the same number of chairs are arranged
