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
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
