cp \: of \: horses = 40000 \\ \\ \\ required \: sp = \frac{110 \times 40000}{100} = 44000

SP \: \: of \: \: two \: \: sold \: \: horses \: \: at \: \: loss = 2( \frac{95 \times 4000}{100}) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2(95 \times 40) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 3800 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 7600

Now,

Wished \: \: SP \: \: of \: \: remaining \: 7 \: horses = 44000 - 7600 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =66400

And,

CP \: \: of \: \: 7 \: \: horses = (4000 \times 7) = 28000

Then,

Required \: \: Profit(in \: \: Rs) = (66400 - 28000) = 38400

.°. \: \: Required\:\: Rate\:\: of\:\:selling\:\:horses= \frac{38400}{7}=5485.71




Hence, The remaining horses should be sold @ of ₹ 5485 to gain profit of 10 % on the total cost.
