A) 203400
B) 194400
C) 198400
D) 205400
Correct Answer: B
Solution :
Sol. [b] Let the two numbers be a and b. |
Given,\[LCM(a,b)+HCF(a,b)=1260\] ...(1) |
and \[LCM(a,b)=900+HCF(a,b)\] |
\[\Rightarrow \,\,\,\,\,\,\,LCM(a,b)-HCF(a,b)=900\] ...(2) |
On solving (1) and (2). we have |
\[LCM(a,b)=1080\]and \[HCF(a,b)=180\] |
We know that. product of two numbers \[HCF\times LCM\] |
\[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,a\times b=180\times 1080=194400\] |
