Question

A man sells a Tv set for rs 33000 and makes a profit of 10% .he sell another tv at a loss of 20 % .if on the whole he neither gain nor loss , find the selling price of tv set ? ​

Answer 1

Step-by-step explanation:

Here, the selling price = 33000

profit made = 10%

therefore original price =»x+10% of x = 33000

x = 33000 - 10% of x

x = 33000- 1/10 of x

10x = 330000-1x

11x = 330000

x = 330000/

= 30000

therefore profit = 33000-30000 = 3000

here, he sells another tv for a loss of 20%

which is selling price - 20%of original price

= 33000 - 20% of 30000

= 30000- ( 20 × 30000)

100

= 33000 - 6000 = 27000

Answer 2

Answer:

12000

Step-by-step explanation:

S.P of 1st TV set = 33000

Profit = 10%

then C.P = 30000

profit of 1st TV set is = Loss of 2nd TV set

Hence, 20% loss = 3000

Loss% = 3000/C.P

20% = 3000/C.P

C.P = 15000

S.P = C.P - LOSS

S.P = 12000
