Question

three consecutive integers are such that when they are taken in increasing order and X 2 3 and 4 respectively they added up to 74 find this number

Answer 1

let the required no.be x,x+1and x+2.

2*x+3(x+1)+4(x+2)=74

2x+3x+3+4x+8=74

9x +11=74

9x=74-11

9x=63

x=63/9

x=7

the required no. are 7,7+1=8,7+2=9
