I believed you are looking for the value of e. The value of e is 16 below is the solution:
A×4 = E, so A=E/4 B/4 = E, so B=4E C+4 = E, so C=E=4 D-4 = E, so D=E+4 and A+B+C+D=100.
Substitute values of A, B, C and D in the equation, we get, (E/4) + 4E + E-4 + E+4 = 100 (E/4) + 4E + 2E = 100 (E/4) + 6E = 100 (E+24E)/4 = 100 E+24E = 100×4 25E = 400 E = 400/25 <span>E = 16</span>
Yes! Just like if I told you three shapes, and that one and two are circles, and then I told you the third was the same as the second, they would all be circles!
