100 glasses are there. A servant has to supply glasses to a
person If he supplies the glasses without any damage he
will get 3 paise otherwise he will loose 3 paise. At the
end of supplying 100 glasses if he gets 270 paise, how many
glasses were supplied safely.
while supplying 90 safe glasses he got 270 paise but what
abt the loss because he has loose 3 paise for unsafe
suppose x is the number for safely reaching glasses
so for damage glasses
complete eq is 3x-3(100-x)=270
solving this we get 95 which is the answer
x= Number of undamaged Glasses.
Y= Number of Damaged glases.
Received Rs.270: 3(X-Y)=270...........(1)
Servent would receive Rs. 300 If he supplies Without
damaging all the glsses. i.e 3X+3Y=300.............(2)
Solving equation (1) and (2)
We get X=95--Glasses which supplied safely.

2.) The payment P(n) that a person receives is a function
of the day n. If P(n) = 2 × P(n - 1) and the person
receives Rs.12 on the day two, then what is the total
payment received by a person for 10 days starting from the
