Two pipe 'A' and 'B' can fill a tank in 34 min and 28 min respectively.A water tank 'C' can empty the tank in 17 min . first 'A' and 'B' are opened. After 10 min. 'C' is also opened. In how much time , the tank is full?
STEP 1 :
Both pipe operate in 1 min.= 1 / 34 + 1 / 28 part of tank
Both pipe operate in 10 min.= 10 * ( 1 / 34 + 1 / 28) part of tank
=10 * (14 + 17 / 476 )part of tank
=310 / 476 part of tank
=155 / 238 part of tank
STEP 2 :
Remaining part of tank = 1 - 155 / 238 part of tank
= 83 / 238 part of tank
STEP 3 :
All pipe operate in 1 min. = 1 / 34 + 1 / 28 - 1 / 17
