Answer 1

Explanation:

as mentioned in question that sum of 3 consecutive integer is 117

let the first integer be x equation(1)

second integer as x+1 equation(2)

third integer as x+2 equation (3)

so the sum of these three equation will be equal to 117

x+x+1+x+2=117

3x+3=117

3x=114

x=38

so first integer is 38

from equation 2 the value of second integer will be 39

from equation 3 he value of third integer will be 40

so he correct answer is a) 38,39,40
