divide by -1??

ye kuch special sa tarika sound kar raha hai....humko bhi sikhao...mein toh modulus ko khol ke karta hun solve...

@ScareCrow28 @mailtoankit aap bhi bata do aap loagon ki koi special tarika ho toh??

Arre I did graphically, hate algebra formulae...(|x+2| - x)/x ko maine (|x+2| - x) 😛 Just looked at magnitude :(

A tank is filled by three pipes with uniform flow. The first two pipes operating simultaneously fill the tank in the same time during which the tank is filled by the third pipe alone. The second pipe fills the tank 5 hours faster than the first pipe and 4 hours slower than the third pipe. The time required by the first pipe is:

@scrabbler
(|x+2|-x)|x+2|Now since you have modulus the RHS can have +ve or negative value
x+22x>2
x>1

x+24x
x
