I think 65

coz 5 square is 25, but propotion is 28 which is more then 25

and 8 square is 64 which and 65 is the only one more then 64

5 : 28 : : 8 : ?

5/28 = 8/x

x = 224/5

x = 44 4/5

The missing number must be x.

And the wrong options are

a 65 b 63 c 62 d 64

65

Let the missing term is x then using propotion

5/28=8/x

Using cross product

5*x=28*8

5x=224

x=224/5

x=44.8

Not either option is correct

65

because if we reverse and fraction it 28/5= 5 3/5 5 common

65/8= 8 1/8 here 8 common

let the required no=x

so,

5/28 = (5*8)/(28*8) = 40/224

and, 8/x = 40/5x

so, 5x=224

x= 224/5 = 44.8
