Question : (320 + 342 + 530 + 915) ÷ (20 + 22 – x + 18) = 43, then the value of $x$ is:
Option 1: 15
Option 2: 11
Option 3: 26
Option 4: 23
Correct Answer: 11
Solution : Given: $(320+342+530+915)÷(20+22-x+18)=43$ ⇒ $\frac{(320+342+530+915)}{(20+22-x+18)}=43$ ⇒ $\frac{2107}{(60-x)}=43$ ⇒ $2107=2580-43x$ ⇒ $-473=-43x$ ⇒ $x=11$ Hence, the correct answer is 11.
