A shopkeeper sold 20 mobile sets of same brand for RS 300000 at the same rate In a week . What is the selling price of each mobile set? If he bought for RS 12500 find his profit or loss percent in the each mobile sets? If each mobile sets is 12 cm long 6cm board and 1 cm thick find the ratio of it length and breadth?

Answer :

1. Selling price and profit per mobile set:

  • Selling price per mobile set: ₹ (300000 / 20) = ₹ 15000
  • Cost price per mobile set: ₹ 12500 (given)
  • Profit per mobile set: ₹ (15000 - 12500) = ₹ 2500

2. Profit percentage per mobile set:

  • Profit percentage = [(Profit per mobile set) / (Cost price per mobile set)] * 100
  • Profit percentage = [(₹ 2500) / (₹ 12500)] * 100 = 20%

3. Ratio of length and breadth of the mobile set (ignoring thickness):

The information about the thickness (1 cm) is irrelevant to finding the ratio of length and breadth. Therefore:

  • Length = 12 cm (given)
  • Breadth = 6 cm (given)
  • Ratio of length to breadth = (Length) / (Breadth) = (12 cm) / (6 cm) = 2:1

Summary:

  • Selling price per mobile set: ₹ 15000
  • Profit per mobile set: ₹ 2500
  • Profit percentage: 20%
  • Ratio of length to breadth: 2:1 (dimensions of the mobile set are not essential for this calculation)

Answer:

Rs 300000/20=Cost of each mobile

=Rs.15000

SP=Rs15000

CP=Rs12500

Profit=SP-CP

=15000-12500

=2500

Profit percet = 2500/12500*100

=20%

Length =12 cm

Breadth=6cm

Ratio of length and breadth =12/6

=2:1
