Sum of three positive integer is 12.Product of these 3 integers would be maximum if these numbers are (select any one out of these ten options)

OPtion

1) 4,5,3
2) 2,4,6
3) 4,5,4
4) 10,1,1
5) 8,2,2
6) 8,3,1
7) 5,3,3
8) 4,5,5
9) 4,9,1
10) 7,3,2

Solution

If we solve 4*4*4, we would get 64(max) but this option is not present there so out of given 10 options 4+5+3 =12
Product = 60 (max)

Correct Option: 1 Best Solution (14)

RajiniRaja S   13 years AGO

only 6 option will give sum 12, and the option 1
will give maximum product.

1) 4+5+3=12 and 4*5*3=60
2) 2+4+6=12 and 2*4*6=48
4) 10+1+1=12 and 10*1*1=10
5) 8+2+2=12 and 8*2*2=32
6) 8+3+1=12 and 8*3*1=24
10) 7+3+2=12 and 7*3*2=42

(1)4,5,3 sum= 12 product=60
2) 2,4,6 sum= 12 product=48
3) 4,5,4 sum= 13
4) 10,1,1 sum= 12 product=10
5) 8,2,2 sum= 12 product=32
6) 8,3,1 sum= 12 product=24
7) 5,3,3 sum= 11
8) 4,5,5 sum= 14
9) 4,9,1 sum= 12 product=36
10) 7,3,2 sum= 12 product=42

option 1 will be right answer

product of 3 numbers will be maximum when they are
= sum / 3 = 12/3 = 4
then the max possible product will be 4*4*4 = 64
other than that product will be max. when numers are as close to 4.
so answer will be 1) 4,5,3
product will be 60
