Question

पांच लगातार सम संख्या A B C D और E का औसत 52 हैं तो B और E का गुणनफल क्या होगा ​

Answer 1

Answer:

B×E = 2800

Explanation:

(A+ B+C+D+E)/5 = 52

according to question

B = A+2

C= B+2 = A+4

D = C+2 = 6+A

E = D+2 = A+8

=> (A + (A+2) +(A+4) +(A+6) + (A+8) = 52×5

=> 5A + 20 = 260

=> 5A = 260-20=240

=> A = 240/5

=> A = 48

now

B = A+2

=> B=48+2 = 50

E = A+8

=> E = 48+8 = 56

B×E = (50)×(56)

=> 2800
