hello,
given that S.P is 80 and a toothbrush of 11 is sold free
total SP is 80+0=80
let the CP of tea be x
he bought toothbrush also of 11
total CP=x+11
we know that SP=[(100+profit%)/100×CP]
∴80=[(100+15)/100×(x+11)]
80=115/100×(x+11)
x+11=8000/115
x+11=69.56
x=69.56-11
x=58.56
therefore,the cost rice of tea bag is 58.56 rupees
hope this helps,if u like it please mark it as brainliest
