Sum of three positive even integers is 30 and their product is 960. Sum of the two smaller integers will be?

• let three even numbers is x,x+2,x+4then
  3x+6=30=>x=8 then series is 8,10,12 then product:8*10*12=960.
  small digit sum is:8+10=18

  Sum of three positive even integers is 30 ... 8+10+12
  and their product is 960-- 8*10*12
  . Sum of the two smaller integers will be 8+10=18

• let the 1st digit be x
  now x+(x=2)+(x+4)=30
  we get x=8
  then 8 +10=18

• three even no be (x+2),(x+4),(x+6)
  then there sum is
  (x+2)+(x+4)+(x+6)=30
  so x is 6
  sum of smaller no is (x+2)+(x+4)=6+2+6+4=18

• it hasn't been mentioned that the 3 integers are consecutive!
  >>so, since the '0' in '960' can only be present if AxBxC contains '10' as an integer. rest two integers' product has to be 96. 12x8 is the only possibility within the given constraints.
  thus, 8, 10, 12 are the integers and 18 is the total.

• ans=18
  hence numbers are 8,10,12
  8+10+12=30
  8*12*10=960
