If a number is decreased by 30 and divided by 12, the result is 20. What would be the result if 200 is subtracted from the number and then it is divided by 14?

If a number is decreased by 30 and divided by 12, the result is 20. What would be the result if 200 is subtracted from the number and then it is divided by 14? Correct Answer 5

Let the number be x.

∴ (x – 30)/12 = 20            

⇒ x – 30 = 20 × 12           

⇒ x = 270

Result = (270 – 200)/14   = 5
