Solution -
SP of first cow = 9900
If he gained 10%.
CP = (SP × 100) / (100 + gain %)
CP = (990000) / (110)
CP of first cow = Rs.9000
Profit = SP - CP
Profit = 9900 - 9000
Profit = 900
Similarly,
SP of second cow = 9900
If he lost 20%.
CP = (SP × 100) / (100 + loss %)
CP = (990000) / (80)
CP = 12375
CP of second cow = Rs. 12375
Loss = CP - SP
Loss = 12375 - 9900
Loss = 2475
So,
The net loss = 2475 - 900
= 1575
Hence,
The correct answer is option (d) none of the above.
