<human>:  Carla had 400 chickens on her chicken farm. However, 40% of the chicken died due to a certain disease. How many chickens were there if she bought ten times as many chickens as the number that died due to disease?
<bot>: How many chickens died due to disease? ** If Carla had 400 chickens on her chicken farm, the number that died is 40/100*400= <<40/100*400=160>>160
How many chickens were there after the disease? ** Carla remained with 400-160=<<400-160=240>>240 chickens.
How many chickens did Carla buy? ** Carla then bought 10*160= <<10*160=1600>>1600 new chickens.
How many chickens did Carla have after buying? ** The total number of chicken that Carla had now is 1600+240=<<1600+240=1840>>1840
