posting the question third time..plzzz solve it?
Solve for x ???
58 : 89 :: 63 : x
A) 105
B) 208
C) 247
D) 221
Here there is no concept of means and extremes..
For example,
8 : 9 :: 64 : 25
Here there is a sequence i.e.
2^3 : 3^2 :: 4^3 : x
X = 5^2
Similarly solve my question...!!!

58 : 89 :: 63 : x
58 is to 89 as 63 is to x.
This can be written (and though of) another way:
58/89 = 63/x
Cross-multiply:
58x = 63 * 89
x = (63 * 89)/58 = 96.672413793103448…
So, none of the given options fits … unless I've got everything topsy-turvy! :)
Can you check the figures?

According to ur options i think the answer is 105.
Becoz,
Sqtr of 59 is 7.68 rounded to 7.9
cube root of 89 is 4.46 rounded to 4.7
Sqrt of 63 is 7.93
Simillarly cube root of 105 is 4.7
therefore answer is 105.
