Question : If (48 ÷ 72 × 3) – [15 ÷ 8 × (40 – 32) – 10] + 2P = 6 ÷ 2, then find the value of P?
Option 1: 3
Option 2: 4
Option 3: 2
Option 4: 1
Correct Answer: 3
Solution : (48 ÷ 72 × 3) – [15 ÷ 8 × (40 – 32) – 10] + 2P = 6 ÷ 2 ⇒ ($\frac{2}{3} × 3) – [\frac{15}{8} × 8 – 10] + 2P = 3$ ⇒ 2 – [15 – 10] + 2P = 3 ⇒ 2 – 5 + 2P = 3 ⇒ – 3 + 2P = 3 ⇒ 2P = 6 ⇒ P = 3 Hence, the correct answer is 3.
