Question : 9 of 200

Marks: +1, -0

II. a and b are divisible by 3.

if the statement I alone is sufficient to answer the question.
if the statement II alone is sufficient to answer the question.
if both the statements I and II are sufficient to answer the question but neither statement alone is sufficient.
if both the statements I and II together are not sufficient to answer the question and additional data is required.

Solution:

Given: a × b =270

We know that,

LCM × HCF = Product of two numbers.

I Given: GCD of ‘a’ and ‘b’ is 9.

∴ We can find LCM

=\frac{\text{product of numbers}}{\text{GCD}}

NOTE : There appears to be some error in the given data.

Given: GCD = 9

∴ we can write ‘a’and ‘b’ as 9x and 9y

Product:

(9x)(9y)=81xy

But the given product 270 is not divisible by 81.
