Question

Mr Mehta purchased a video for Rs 20000 and a television for Rs 30000. On the video he lost 5% and on the television he gained 8%. Find his total gain or loss.​

Answer 1

Answer:

Gain = 2.8%

Step-by-step explanation:

For Video:

CP of video = Rs. 20000

Loss of 5% = 20000 * (5/100)

       

                 = 1000

Selling price = CP - lost

= 20000 – 1000

= Rs. 19000

For TV

CP of TV = Rs. 30000

Gain by 8% = 30000 * (8/100)

                   = 2400.

Selling price = cost price + Profit

                     = 32400.

Total cost price = 20000 + 30000 = 50000

Total selling price = 19000 + 32400 = 51400

Here, CP > SP. So, Gain has occurred.

Gain = Selling price - Cost price

        = 51400 - 50000

        = 1400

Gain% = (Gain/CP) * 100

           = (1400/50000) * 100

 

           = 14/5

           = 2.8%

Therefore, Gain = 2.8%

Hope it helps!

Answer 2

Video=>

CP=20000

loss=5*20000/100

      = 1000

SP=20000-1000

    =19000

TV=>

CP=30000

loss=8*30000/100

      = 2400

SP=30000+2400

    =32400

therefore,

total CP=20000+30000

            =50000

total SP=19000+32400

            = 51400

therefore, profit=51400-50000

                        =1400

therefore, profit%=(1400/50000)*100

                           =2.8% gain.....
