Answer 1

Answer:

Answer:

Given

LCM and HCF of two numbers = 12 & 72

Product of two numbers = 12 × 72 => 846

Let one number = A

then the other number = 60-A (as the sum of two numbers is 60)

From the above...

=>A(60-A) = 12×72

=> 60A - A² = 846

By factorisation

=> A²-60A+846 = 0

=> A² -24A-36A+846 = 0 ( +846 => -24 × -36)

=> A(A-24) - 36(A-24) = 0

=> (A-24)(A-36) = 0

=> A = 24 or 36

If A = 24 then the other Number is 36.... So the answer is (b)..
