100 wine glasses so,3*100=300.if a glass is broken then 9paisa is deducted + he will also not get the 3paisa he was getting for safe delivery so in total he will loss 9+3=12paisa for 1glass broken. he gets 240paisa i.e. 60paisa loss so,total no. of glass = 60/12 = 5.(ans)

Let the no. of broken glasses be x,
Now,as per ques,in paisa
3*(100-x)-9*x=240
=>x=5
therefore,no.of broken glasses=5

if broken=x
unbroken=100-x
so, 3(100-x)-9x=240
x=5

bindu  (10 years ago)

let no.of glasses safely reached are x and broken are y so 3x-9y=240
and we know x+y=100
by solving we get y=5 so 5 are broken

Ans is 5
If he broken 5 glass means he should pay=Rs.0.45 paisa(5*9paisa)

total glass 100.
95(delivered safely)*3 = 285 paisa(he got)
5(broken)*9(paisa)=45 paisa(he gave)

let k be the wine bottle which he delivered safely.so, 100-k will be the wine bottle which is broken.
so,as he is getting 3 paise for each wine bottle and 9 paise has been deducted for each broken bottle.
3*k-9*(100-k)=240
k=95.so,no of broken bottle will be (100-k)=5
