Question

Two numbers are in ratio 3:4 and the product of their lcm and hcf is 10800.The sum of the number is

Answer 1

Answer:

Step-by-step explanation:

Let the numbers are 3x and 4x

LCM x HCF =3x*4x=10800 (given)

12x²=10800

x²=10800/12=900

x= ±30

so the sum of numbers=3x+4x=7x

=7*(±30)=±210

Answer 2

Answer:

the answer is 210

Step-by-step explanation:

3:4 is the ratio take 3 &4 multiply it

answer is:12²×x²=3:4=10800

for the first number divide 12/10800=900

=¥30

so, hence the answer is 210
