Question

Average of 4 consecutive no is 42.5 than smallest no. of 18

Answer 1

HEYA MATE, HERE IS UR ANSWER

$<b><i>Let the numbers be x ,x+1,x+2 and x+3$

Average =$\frac {Sum\: of\: all\: the\: numbers}{total\: numbers}$

42.5=$\frac {x+x+1+x+2+x+3}{4}$

42.5=$\frac {4x+6}{4}$

By cross multiplication

42.5×4=4x+6

170=4x+6

170-6=4x

164=4x

$\frac {164}{4}$=x

41=x

So the numbers are

x=41

x+1=42

x+2=43

and x+3=44
