• # question_answer If the sum of LCM and HCF of two number is 1260 and their LCM is 900 more than of their HCF, then the product of two numbers is A)  203400          B)  194400       C)  198400                      D)  205400

Let HCF be$x$ Then LCM$=900+x$ $900+x+x=1260$ $900+2x=1260$ $2x=360$ $x=180$ Nos. are 180, 1080 $\therefore$Product$=180\times 1080=194400$
