let cp of horse be x
and cp of cart be y
then
horse sp=90*x/100=9x/10
cart sp=120*y/100=6y/5
now he say thru these no loss no gain mean cp of both equal to sp of both
=> x+y=(9x/10)+(6y/5)-----(1)
again
horse sp=95*x/100=19x/20
cart sp=105*y/100=21y/20
now at this time he suffer loss of 10 rs mean
cp=sp+10
x+y=19x/20+21y/20+10-----(2)
solving eq 1 and 2 u will get the ans x=400 & y=200

Let the cost price of horse be 'x'
Let the cost price of cart be 'y'
Case 1: 10% loss in horse = 0.1x
20% gain in cart = 0.2y
Since they are equal, 0.1x=0.2y or x=2y or x-2y=0 ................(1)
Case 2: 5% loss in horse = 0.05x
5% gain in cart = 0.05y
0.05x=0.05y+10 or 5x=5y+1000 or 5x-5y=1000 .................(2)
On solving (1) and (2) we get y=200 & x=400
