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

Let us assume 
A= 4
B=64
C=12
D=20
so, A+B+C+D=100.
Now by putting these values in equation we can find the value of E.
Ax4=4x4=16
B÷4=64÷4=16
C+4=12+4=16
D-4=20-4=16
Hence the value of E is 16.
