π Bihar
Answer: Option B
Explanation:
According to the question,
a/b = 4/1
We know,
Product of means = product of extremes
.β’. a Γ 1 = b Γ 4
a = 4b
(a - 3b)/(2a - b) [Replace the value of βaβ as 4b.]
= (4b - 3b)/(8b - b)
= b/7b
= 1/7 (Ans.)
Simple method :
According to the question -
a = 4 and b = 1
(4 - 3)/(8 - 1)
= 1/7 (Ans.)
