If 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 ?

Its Simple maths A = E/4 B = E*4 C = E-4 D = E+4 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

a=4 b=64 c=12 d=20

Ans: E=16

If;

A x 4 = E

B / 4 = E

C + 4 = E

D – 4 = E

A + B + C + D = 100

Then;

E = ?
