Step-by-step explanation:
For a total sale Rs.7000,
3000Xx1003000Xx100+ 4000Xy1004000Xy100=1100
=>30x+40y=1100
=>3x+4y=110-----(i)
For a total sale of Rs.11000
3000Xx1003000Xx100+ 8000Xy1008000Xy100=1660
30x+80y=1660
=>3x+8y=166 ------(ii)
By equation (ii)-(i),
4y = 166-110 =56
=>y= 564564=14%
From equation(i),
3x+14x4=110
=>3x=110-56=54
=>x= 543543= 18%
