A, B, C, D and E play a game of cards. A says to B, “If you give me...

According to the given information,

$B - 3 = E$~--------$( 1 )$
$B + 3 = D$~-------$( 2 )$
$A + B = D + E + 10$~-----$( 3 )$
$B = C + 2$~--------$( 4 )$
$A + B + C + D + E = 133$~------$( 5 )$

Now, if we add~equations~$( 1 )$~and $( 2 )$, we get,
$2B = E + D$~--------$( 6 )$

Substituting equation~$( 6 )$~in~$( 3 )$,

$A + B = 2B + 10$~ ~
$A = B + 10$~--------$( 7 )$

Substituting equations~$( 4 ) , ( 6 )$~and~$( 7 )$,~in equation~$( 5 )$, we get,

$( B + 10 ) + B + ( B - 2 ) + 2B = 133$

$5B + 8 = 133$

$5B = 125$

$B = 25$

Therefore, B has~$25$& cards.
