Answer 2

Answer:

35.425/-

you bought 250 tubes, each price 30

you bought it by (250×30)=7500/-

15 are defused. you have now (250-15)=235.

you have to gain 10% on 7500 /-

so, 7500×(110/100)= 825. that is your profit.

now you have to earn 7500+ 825= 8325/- on 235 tubes.

235 tubes RS is 8325.

1 " " " 8325/235

= 35.425/-.(ANS)
