Read Solution (Total 8)
-
- (x+(x+2)+(x+4)+(x+6))/4=27
x=24.......24,26,28,30
30 is largest - 12 years agoHelpfull: Yes(3) No(0)
- four consecutive even numbers 24, 26, 28, 30
avg is 27, largest is 30 - 12 years agoHelpfull: Yes(1) No(3)
- Ans:30
consecutive even number=x,x+2,x+4,x+6/4=27
4x+12=108
x=24
large number=24+6=30 - 9 years agoHelpfull: Yes(0) No(0)
- LET 1ST NUMBER IS a THEN
(a+(a+2)+(a+4)+(a+6))/4=27
a=24
LARGEST NUMBER IS 24+6=30 - 9 years agoHelpfull: Yes(0) No(0)
- let the smallest even no. is x
{(x)+(x+2)+(x+4)+(x+6)}/4=27
x+3=27
so x=24.
so the largest even no. will be 24+6=30
so option is (c) - 8 years agoHelpfull: Yes(0) No(0)
- (x+(x+2)+(x+4)+(x+6))/4=27
4x+12=108
x=24
largest number= x+6= 24+6= 30 - 7 years agoHelpfull: Yes(0) No(0)
- c.30
30+28+26+24=108/4=27 - 7 years agoHelpfull: Yes(0) No(0)
- (x+x+2+x+4+x+6)/4=27
4x+12 =108
4x=108-12
4x=96
x=24
largest number = x+6=24+6=30 - 7 years agoHelpfull: Yes(0) No(0)
