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, ie, 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.......(1)
put the values of a,b,c, and d into equation (1). we get,
(e/4)+4e+e-4+e+4 =100
(e/4)+6e =100
e(24+1)/4=100
e=100×(4/25)
e=400/25
e=16
therefore, the value of e is 16.
