- i think it is two more than the sum of other two
a-b=3 and b-c=3 then a-c=6
a=3c
if a=2+b+c
a=2+((2a/3)+3)
then go by options it is 15 - 13 years agoHelpfull: Yes(4) No(2)
- c = 2+(a+b)..........(ii)
it is given that 2 times the sum of other two children
it should be given as c=2(a+b) - 8 years agoHelpfull: Yes(2) No(0)
