Solve for x ... On sequences ??? §?

The may be A)105

Because,

58/89=0.65168539325842696629213483146067

is equal to 63/x

63/105=0.6

63/208=0.30288461538461538461538461538462

63/247=0.25506072874493927125506072874494

63/221=0.28506787330316742081447963800905

of these 63/105 is similar to 58/89

so the answer is 63/105

58 : 89 :: 63 : x

Solve for x.

x

= (89*63)/58

= 96.67

The proportion a/b = c/d was formerly written

a : b :: c : d and is read as "a is to b as c is to d."

In this form it is customary to call b and c the means

and a and d the extremes.

or 58/89=63/x

x=63*89/58

none of the options seem to be the ans.

It is given that this two ratios are in proportion so.;

Product of Mean = Product of Extreme

=> 58*x = 89*63

=>x = 89*63/58

=>x = ............(96.6)

none of the options are correct.

set it up like a fraction and then cross multiply... but just looking at it, I think the answer is A. 58 is more than half of 89, so 63 has to be more than half of the answer.

I think its B) 208
