Answer Key-
Q-(1) Sol-(2)
(A+B+C) one hour work
Therefore, volume filled by pipe (A+B+C) = 
Volume of tank left to be filled
= 
(A+B) one hour work
=
For C’s one hour work = 1/6-1/12= 1/12 l/hr.
=
hr.
hr.
Hence C alone can fill the tank in = 12 hours.
Q-(2) Sol-(1)
Q-(3) Sol-(1)
Q-(4) Sol-(3)
From eqn. (I) and (II),
y = 11
x = 7
x < y
Q-(5) Sol-(4)
Q-(6) Sol-(3)
From eqn (I) and (II),
x = 5 (Approx)
y = 13 (Approx)
x < y
Q-(7) Sol-(2)
Percent = 
(approx.)
(approx.)
Q-(8) Sol-(1)
Difference = 686 – 365 = 321
Q-(9) Sol-(3)
Average number = 
Q-(10) Sol-(4)
