Read Solution (Total 6)
-
- answer is 11

so 5+6=11
by option we can do this type of question - 12 years agoHelpfull: Yes(13) No(0)
- option (b) 11 is correct answer
The three consecutive integers are:5,6,7
5*6*7=210
so the sum of two smaller integers is:5+6=11 - 12 years agoHelpfull: Yes(3) No(1)

- 5*6*7=210
5+6=11 - 12 years agoHelpfull: Yes(0) No(0)
- prime factor of 210 is 2,3 ,5,7 we have to select 3 no out these factor combination will be {(6,5,7),(10,3,7),(14,5,3),(2,15,7),(2,5,21),(2,3,35)}
now see the answer it says sum of two smaller digit hence ,B will be the answer

- let 1st integer =y
so,2nd=y+1
3rd=y+2
y*(y+1)*(y+2)=210
y^3+3y^2+2y=210
solving y=5
no=5,6,7
ans.>>>>>11 - 10 years agoHelpfull: Yes(0) No(0)
