Question

If 3X = 4Y = 57, then find X:Y: Z.​

Answer 1

Hey,

here ur answer,

3x=4y=5z = k

x= k/3 ,y= k/4, z= k/5

x : y: z = k/3:k/4: k/5 = 1/3 : 1/4: 1/5

x: y : z = 20 : 15 : 12

Answer 2

Answer:

20:15:12

Step-by-step explanation:

    3X = 4Y                              ;     4Y = 5Z

or,   X =  4Y/3                          or,   Z =  4Y/5

∴X:Y:Z = 4Y/3:Y:4Y/5

           =1/3:1/4:1/5

           = (1/3)×60:(1/4)×60: (1/5)×60

           = 20: 15: 12
