Question
If a number is decreased by 8 and divided by 12, the
result is 16. What would be the result if 10 is subtracted from the number and then it is divided by 5.Solution
Let the number be x. According to the question, (x-8)/12 = 16 x – 8 = 192 , x = 200 Now, ∴ Required resultant = (x-10)/5  = (200-10)/5 = 190/5 = 38Â
