Question

$4$ is added to a number and the sum is multiplied by $5$. If $20$ is subtracted from the product and the difference is divided by $8$, the result is equal to $10$. The number is __________.

• A. $16$
• B. $12$
• C. $8$
• D. $20$

Answer 1

Answer: (A)

$16$

According to question, the given condition is

$\frac{\left(\right[(x+4)\times 5]-20)}{8}=10$

$\left(\right[(x+4)\times 5]-20)=80$

$\left[\right(x+4)\times 5]=100$

$x+4=20$

$x=16$
