Question

Sum of LCM and HCF of two number are 50 and their LCM is 20 more than the HCF, the product of two numbers will be :

• A. 425
• B. 525
• C. 325
• D. 925

Answer 1

The correct option is B 525

As per question

LCM+HCF=50$-\left(1\right)$

and LCM-HCF=20$-\left(2\right)$

On solving eqs.(1) and (2)

we get, LCM=35

and HCF=15

therefore,

Product of two numbers=$LCM\times HCF$

=35$\times$15

=525
