Question

Let the sum of the digits of a number X be represented by Sum(x). For example Sum(256)
= 2 + 5 + 6 = 13. Suppose A and B are two 3-digit numbers, what could be the maximum
value of Sum(A) Sum (B)?
1) 24
2) 26
3) 27
4) 29​

Answer 1

explanation.....

1)).

sum(a)=sum(743)= 14

sum(b)= sum(834)= 15

sum(a)+sum(b)= 14+15= 29

so, 29 could be the maximum value of Sum(A) +Sum (B
