Given : p/2q = 11/5
To Find : (p - 2q)/(p + 2q)
1️⃣ 3/8
2️⃣ 8/3
3️⃣ 2/9
4️⃣ 9/2
Solution:
p/2q = 11/5
Subtracting 1 from both sides
=> p/2q - 1 = 11/5 - 1
=> (p - 2q)/2q = 6/5
=> p - 2q = 2q(6/5) Eq1
p/2q = 11/5
Adding 1 from both sides
=> p/2q + 1 = 11/5 - 1
=> (p+ 2q)/2q = 16/5
=> p + 2q = 2q(16/5) Eq2
Eq1 / Eq2
=> (p - 2q)/(p + 2q) = 2q(6/5) / 2q(16/5)
=> (p - 2q)/(p + 2q) = 6/16
=> (p - 2q)/(p + 2q) = 3/8
3/8 is the correct answer
