Answer:
milkman buys two cows for Rs. 3000. He sells first cow at a profit of 22% and the second cow at a loss of 8%. What is the SP of second cow if in the whole transaction there is no profit no loss?
Let purchase price of first cow be x, therefore purchase price of the second cow will be
3000 - x.
Sale price of 1st cow = x + 22x / 100
Sale price of 2nd cow
= 3000 - x - 8 (3000 - x) / 100
As per statement
3000 = x + 22x/100 + 3000 - x - 8 (3000 - x)/100
3000= x + 22x/100 + 3000 - x - (24000 + 8x) /100
3000=x + 22x/100 + 3000-x -24000/100+ 8x/100
3000–3000 + 240 = x + 22x/100 - x + 8x/100
240= 22x/100 + 8x/100
240 = (22x + 8x)/100
240= 30x /100
Cross multiplication
30x = 240 × 100
30x=24000
x = 24000/80
x = 800
Sale price of 2nd cow =
3000 - x = 3000 - 800
= Rs 2200
Answer the sale price of 2nd cow is Rs 2200
