Question

if
a x 4 = e
b / 4 = e
c + 4 = e
d - 4 = e
and
a+b+c+d = 100

THEN
what is value of 'e'

Answer 1

a×4 =e,
a=e/4.

b/4 =e,
b= 4e.

c+4=e,
c=e-4.

d-4=e,
d= e+4.

a+b+c+d=100.

put values of a,b,c and d into 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+24 e= 100×4
25 e =400
e =400/25
e=16.
Value of e is 16.
