Answer:
X = 8000
Step-by-step explanation:
a tv set is being sold for Rs. x in Delhi. A dealer went to Chandigarh and bought the TV set at 20% discount (from the price of Delhi). He spent Rs. 600 on transport. Thus he sold the set in Delhi for making (100/7)% profit. Find the value of x.
Selling Price = X Rs
Bought at 20 % Discount = X - (20/100)X = 0.8X Rs
Transport Cost = Rs 600
Cost Price = 0.8X + 600 Rs
Profit Made = 100/7 % = ((100/7)/100)(0.8X + 600)
= (0.8X + 600) /7
Selling Price = 0.8X + 600 + (0.8X + 600) /7
= (0.8X + 600)*8/7
(0.8X + 600)*8/7 = X
=> 6.4X + 4800 = 7X
=> 0.6X = 4800
=> X = 8000

Answer:
Step-by-step explanation:
20%==1/5
4/5*x+600)+1/7*(4/5x+600)==X
4/5x+600+4/35x+600/7==x
32x/35+4800/7==x
3x/35==4800/7
X===4800*35/21==8000Rs
