A company figured it needed 37.8 sq.feet of carpet for its
reception room. To allow for waste, it decided to order 20% more
material than needed. Fractional parts of sq.feet cannot be ordered.
At Rs.9/- a sq.feet, how much would the carpet cost?

• Needed Carpet is 37.8
  Total material ordered = 37.8+(20% of 37.8)
  = 37.8 + ((20/100)37.8)
  = 37.8 + 7.6
  = 45.4 (Round off to 46)
  Given that
  carpet cost per sq.feet = 9
  total cost = 9*46
  =414
  ans is 414

• 37.8*1.20=226.8/5=45.36
  ignoring fractional part,we get 45
  therefore 45*9=405

• 37.8+(0.2*37.8)=45.36
  therfore,45*9=405

• rs405
  37.8+20% of 37.8=45.36=45(appx)
  9*45=405

• WE need 20% extra of what is required. so . total amount of carpet required = 37.8+(37.8*20/100)=37.8+7.56=45.36 sq.feet.
  BUT we are not allowed to order in fraction. So we ROUND OFF 45.35 sq. feet to 45 sq.feet.(nearest decimal value).
  hence, total amount to be paid = 45*9=405. ANSWER IS Rs. 405
