Question

A x 4 = E
B ÷ 4 = E
C + 4 = E
D - 4  = E
___________
& A + B + C + D = 100

Challenge
*what is the value of E ?*

Answer 1

So,A+B+C+D = 100
=> (E/4)+(E*4)+(E-4)+(E+4) =100
=> (E/4)+4E+E+E+4-4 =100
=> E/4+4E+2E =100
Now taking LCM as 4
E+16E+8E/4 = 100
25E = 100*4
E = 400/25
E = 16

Hope it helps....

Answer 2

4×4=16
64÷4=16
12+4=16
20-4=16

4+64+12+20=100
so, the value of E is 16.
