Question

The sum of squares of three number which are in the ratio 2:3:4 is 725. Then whst is the largest number?

Answer 1

hey, here is your answer

Let 2x, 3x and 4x be three numbers .

therefore, (2x^2) + (3x^2) + (4x^2) = 725

29x^2 = 725

x^2 = 725/29

x^2 = 25

x = 5

therefore, largest number = 4x

= 4(5)

= 20

hope it is useful for you

Answer 2

(2x)^2 + (3x)^2 + (4x)^2 = 725

29 x^2 = 725

x^2= 725/29

x^2=25

x= 5

Hence the greatest no. is 20
