If b is one-fourth of a, then what is the value of $$a+b/\sqrt{ab}$$ ?

(A) 1/5
(B) 1/3
(C) 1/2
(D) 3/2
(E) 5/2

Given, b is one-fourth of a
implies b = a/4

$$a+b/\sqrt{ab}$$ =$$(a+a/4)/ \sqrt{a*a/4}$$ = $$(5*a/4)*(2/a)$$
= 5/2
Option E is correct Re: If b is one-fourth of a, then what is the value of a + b/ab ?   [#permalink] 11 Apr 2019, 00:16
