Answer 2

Heya,

57:85::57:x

Product of mean is equal to product of extreme. [product of mean= product of extreme]

Therefore,

57×x = 85×57
57x = 85×57 [When 57 is swifted to the opposite side it changes into division (multiplication changes into division)]

So,

x= 85×57/57 [57 and 57 gets cancelled]

Hence,

x= 85

Hope my answer helps you :)
