Q. The Average of 5 Consecutive even no A,B,C,D,E is 52. What is the Product of B & E ?

Option
a) 2912
b) 2688
c) 3024
d) 2800
e) None of these

• d)2800
  x+(x+2)+(x+4)+(x+6)+(x+8)/5=52 ->(5x+20)/5=52 ->x=48
  So A=48,B=50,C=52,D=54,E=56
  Product B*E=50*56=2800

• Let the numbers be (a-4) , (a - 2) , a , (a + 2) , (a + 4)
  
  => Average = 5a / 5 = 52
  => a = 52
  
  => B * E = (a - 2) * (a + 4) = a^2 + 2a - 8
  => B * E = 2704 + 104 - 8 = 2800

• a=48, b=50, c=52, d=54, e=56 then a+b+c+d+e/5=48+50+52+54+56/5=52 therefore b*e=50*56=2800

• According to given question,the sum of numbers = 52*5=260
  As it is given that ,the numbers are consecutive,it means they are in AP.
  so, (5/2)(2A+(5-1)2)=260
  A=48
  so, A=48 B=50 C=52 D=54 E=56
  
  SO, B*E=50*56=2800
  
  d IS THE RIGHT ANSWER.

• let the first no be x and other consecutive even no be:x+2,x+4+x+6,x+8
  average=x+(x+2)+(x+4)+(x+6)+(x+8)/5=52
  5x+20=5*52
  5x+20=260
  5x=240
  x=A=48
  B=50
  E=56
  B*E=50*56=2800

• ans is option d)2800
  
  average of 5 consecutive even number is 52
  52 is the middle number
  A B C D E
  48 50 52 54 56
  
  product of B&E =50*56 == 2800

• let x be an even no.
  then x+2,x+4,x+6,x+8 will be five consecutive even nos.
  now,
  add
  (x+x+2+x+4+x+6+x+8)/5=52
  5x+20=270
  5x=250
  x=50
  a=50,b=52,c=54,d=56,e=58
  52*58=3016
  ans)none of these

• A+B+C+D+E = 52*5=260
  
  ANS - None of these

• let first number is x.
  then 5 numbers are x,x+1,x+2,x+3,x+4.
  average is x+x+1+x+2+x+3+x+4/5=52;
  5x+10/5=52;
  5x+10=260;
  5x=250;
  x=50;
  five consecutive numbers are 50,51,52,53,54
  product of b&e is 51*54=2754
  
  answer is e
• 11 years agoHelpfull: Yes(0) No(0)
• the consecutive even numbers are 48,50,52,54,56
  and the product of b&e is 50*56=2800
  ans is 2800

• Let the numbers be (a-4) , (a - 2) , a , (a + 2) , (a + 4)
  
  => Average = 5a / 5 = 52
  => a = 52
  
  => B * E = (a - 2) * (a + 4) = a^2 + 2a - 8
  => B * E = 2704 + 104 - 8 = 2800
