The management wanted to put equal and maximum number of
chairs in each row. Find the number of chairs in each row?​

Answer 1

Answer:

45

Step-by-step explanation:

to find the highest no of chairs possible.. ee have to find HCF of 225,315 and 135.

225 = 5*5*3*3

315= 5*3*3*7

135=5*3*3*3

HCF = 5*3*3 = 45

Answer 2

The number of chairs in each row is 45.

Step-by-step explanation:

In order to find the required number of chairs in each row (which meets the conditions given in the question), we find the HCF of 225, 315 and 135.

Here,

• 225 = 3 × 3 × 5 × 5
• 315 = 3 × 3 × 5 × 7
• 135 = 3 × 3 × 3 × 5

So, HCF = 3 × 3 × 5 = 45.

Thus there will be 45 chairs in each row.
