Question

Suma a trei nr este 2603.Primul nr inseamna trei sferturi din al 3 lea,iar acesta o treime din al doilea.Care sunt nr ?

Answer 1

a+b+c=2603
3/4*c=a=3c/4=a
1/3*b=c=b/3=c
=3*b/3/4+b+b/3=2603
=3b/3/4+b+b/3=2603
=3b/3*1/4+b+b/3=2603
=3b/[3*4]+b+b/3=2603
=3b/12+b+b/3=2603
=3b/12+12b/12+4b/12=2603
=19b/12=2603
=19b=12*2603
=19b=31236
=b=1644
=c=1644/3=c=548
=a=[3*1644/3]/4
=a=1644/4=411
