Question

the product of two number is 1200 and their difference is 40 find the number

Please give answer step by step ​

Answer 1

Answer:

Step-by-step explanation:

LCM * HCF = PRODUCT OF NUMBERS. ( This is valid for two numbers )

=> 40 * HCF = 120

=> HCF =3

Answer 2

If the first no. be x and second be (x - 40)

Then, x * (x - 40) = 1200

=> (x * x ) - ( x * 40 ) = 1200

=> x² - 40x = 1200

=> x² - x = 1200 / 40

=> x = 30

And x - 40 = 30 - 40 = -10

Well I think that there is something wrong with your question.
