Question

A x 4 = E B ÷ 4 = E C + 4 = E D - 4 = E ___________ & A + B + C + D = 100 *what is the value of E ?*

Answer 1

A=E/4
B=4E
C=E-4
D=E+4
A+B+C+D=100
E/4+4E+(E-4)+(E+4)=100
E/4+4E+E-4+E+4=100
E/4+4E+2E=100
E/4+6E=100
E+24E=4*100
25E=400
E=400/25
E=16..Ans...

Answer 2

"A, B, C and D with respect to E

So, A*4=E , thus A= E/4

B/4=E, thus B=4E

C+4=E, thus C=E-4

D-4=E, thus the answer for D=E+4

Now, we know that,

A+B+C+D=100

Therefore,

(E/4) + (4E) + (E-4) + (E+4) = 100

=> (E/4) + (4E) + (2E) = 100

=> (E/4) + (6E) =100

=> (25E/4) = 100

=> E= (100*4)/25

=> E=16

The value of E is 16

=> E= (100*4)/25

=> E=16"
