Question

20. Two numbers are in the ratio 3 : 4 and the
product of their LCM and HCF is 10800.
Find the sum of the numbers.
(1) 190
(2) 70
(3) 210
(4) 200​

Answer 1

Answer:

Product of two numbers= (LCM of that two numbers)×(HCF of that two numbers)

So product of two numbers =10800 which are in the ratio 3:4

Let the numbers be 3x and 4x

So their product,

3x×4x=10800

x=30

So the numbers are 3x=90 and 4x=120

Answer 2

Answer:

Product of two numbers= (LCM of that two numbers)×(HCF of that two numbers)

So product of two numbers =10800 which are in the ratio 3:4

Let the numbers be 3x and 4x

So their product,

3x×4x=10800

x=30

So the numbers are 3x=90 and 4x=120
