​

Answer 1

Answer:

The correct option is D 81

Let the two numbers be x and y.

It is given that:

x

=

54

H

C

F

=

L

C

M

=

162

We know that,

x

×

y

=

H

C

F

L

C

M

⇒

54

y

=

27

×

162

⇒

54

y

=

4374

⇒

y

=

4374

54

=

81

Step-by-step explanation:

but there are not obsane ok 81 so

right answer is [d] none of these

Answer 2

Answer:

x×y=Lcm×Hcf

81×y=162×27

y= 2×27

y=54
