Here is your answer
SP of one Horse is Rs 2970
Gain% = 10%
As we know the formula
CP = SP× 100/(100 + Gain%)
$= \frac{2970 \times 100}{(100 + 10)} \\ = \frac{297000}{110} \\ = 2700$
So CP = Rs 2700

For I I
SP = Rs 2970
Loss% = 10%

As we know the formula
CP = SP× 100/(100-LOSS %)
$= \frac{2970 \times 100 }{(100 - 10)} \\ = \frac{2970 \times 100}{90} \\ = \frac{297000}{9} \\ = 3300$
so CP = Rs 3300

Total CP = 3300 + 2700
= Rs 6000

Total SP = 2970× 2
= Rs 5940

AS SP IS LESS THAN CP SO THERE YOU LOSS

Loss = CP - SP
= 6000 - 5940
= Rs 60

Loss % = Loss× 100/CP
$= \frac{60 \times 100}{6000} \\ = 1\%$
So Man has a loss of 1% on the whole transaction.
