Question

The ratio of two numbers are
3:4 The product of their L.C.M
and H.C.F is 2028, then their sum
is: -​

Answer 1

Product of the LCM and HCF of two numbers is equal to the product of the two numbers.

So,

$3x × 4x = 2028.$

$12x^2 = 2028,$

$x^2 = 2028/12 = 169.$

Answer 2

Answer:

91

Step-by-step explanation:

3x X 4x= 2028

12x^2=2028

x^2= 2028/12 = 169

x = √169 = 13

3x = 3X13 = 39

4x = 4X13 = 52

39+52=91
