Answer 1

Step-by-step explanation:

Total cost price =7800

Let first cost price be x,

second cost price= 7800-x

x(100+4)/100=(7800-x)(100-9)/100

x×104/100=(7800-x)91/100

104x=(7800-x)91

104x+91x=7800×91

195x=7800×91

x=7800×91/195=3640

The cost price of which it is sold for loss 7800-3640=4160

the option (4) is the ans
