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+b+c+d =100........(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.

put the value of a,b,c, and d in equation (1). we get,

(e/4)+4e+e-4+e+4 =100

(e/4 )+4e+e+e =100

(e/4) +4e+2e =100

(e/4)+6e =100

(e+24e)/4 =100
e(25/4) =100

e = 100 ×4/25

e =400/25

therefore, e = 16.

the value of 'e' is 16.
