Question

A farmer bought two cows for 15,000 each. He
sold one at a gain of 6% and on the other he
incurred a loss of 5%. Find the overall gain or
loss %.​

Answer 1

Answer:

0.5%

Step-by-step explanation:

CP of cow 1 = ₹15,000

Gain = 6 percent = 6/100 * 15000 = ₹900

SP = ₹15,900

CP of cow 2 = ₹15,000

Loss = 5 percent = 5/100 * 15000 = ₹750

So, SP = ₹14,250

So, total CP = ₹30,000

Total SP = ₹30,150

So, gain = ₹150

So, gain percent = 150/30000 * 100 = 1/2 percent = 0.5%

Answer: Gain of 0.5 percent.

Answer 2

Step-by-step explanation:

Two cows price = 15000 each

he sold one at gain of 6%

1st cow

sp = cp × (100+gain)/100

15000× (100+6%)/100

150× 106

15900

2nd cow

sp at loss of 5%

cp x 100-5)/100

15000 x ( 100-5)/100

150 x 95 = 14250

Total cp = 15000 + 15000

30000

Total sp = 15900+14250

30150

profit = sp - cp

30150 - 30000

150

profit % = 150/30000

1/2 %
