A. 50
B. 66 2/3
C. 150
D. 200
E. 450

Saurabhminocha · Answer

Its easier to convert percent to a fraction for this question:

150% = 1.5 times or 3/2

a = 3b/2 => 2a = 3b
since 3b is double of a the answer is 200% (D)

AkshdeepS · Answer

Given :

a = \frac{150}{100} * b

a = \frac{3}{2} * b

\frac{a}{b} = \frac{3}{2}

If  a = 3 , then  b = 2  (in ratio)

Say,  x%  of  a = 3b

\frac{x}{100} * 3 = 3*2  (put a = 3 & b = 2)

x =  200 %

ljw1101 · Answer

Given a=150%b, this can be rewritten as:

a=1.5b; apply multiplication on both sides,
2a = 3b

Thus, with 3b, a=2 or 200%

ScottTargetTestPrep · Answer

We have the equation:

a = 1.5b

2a = 3b

2 = 3b/a

200 = 3b/a x 100

Answer: D
