A, B, C, D and E play a game of cards. A says to B, "If you give me three cards, you will have as many as E has and if I give you three cards, you will have as many as D has." A and B together have 10 cards more than what D and E together have. If B has two cards more than what C has and the total number of cards be 133, how many cards does B have ?

Answer: Option
Explanation:

Clearly, we have :

B-3 = E ...(i)

B + 3 = D ...(ii)

A+B = D + E+10 ...(iii)

B = C + 2 ...(iv)

A+B + C + D + E= 133 ...(v)

From (i) and (ii), we have : 2 B = D + E ...(vi)

From (iii) and (vi), we have : A = B + 10 ...(vii)

Using (iv), (vi) and (vii) in (v), we get:

(B + 10) + B + (B - 2) + 2B = 133 5B = 125 B = 25.

How A + B = D + E + 10?

It must be D + E = A + B + 10.

Please explain this clearly.

n = 96.

=> 4n-4 = 96.

=> 4(n-1) = 96.

=> n-1 = 96/4.

=> n-1 = 24.

=> n = 24+1.

=> n = 25.

A+B+C+D+E = 133.

B+3 = D(1).
B-3 = E(2).

B = C+2, C = B-2(3).

A+B = D+E+10 = (B+3)+(B-3)+10(4).

From 1, 2, 3 & 4.

We get...

B+3+B-3+10+B-2+B+3+B-3 = 133.

5B+8 = 133.
5B = 125.
B = 25.

We have,

B - 3 = E .
B + 3 = D.
B=C+2=>C=B-2.

Then,
A+B = D + E+10.
Which we can be done into,

A+B = B-3 + B+3 + 10.
A+B= 2B + 10.

Then lets add all.

A+B+C+D+E=133.
2B+10+B-2+B+3+B-3=133.
5B=133-8.
B=125/5.
B=25 -> we get the answer.

How do you get from,

B-3 = E.
B+3 = D.
to
2B = D+E.

Do you just add them together?

A+B+C+D+E=133
(B+10)+B+(B-2)+2B=133

5B+8(i.e 10-2)=133
5B=133-8
5B=125
B=125/5
B=25.

B=C+2=>C=B-2
2B=D+E=>D=2B-E
(B+10)+B+(B-2)+2B-E+E=133
B+10+B+B-2+2B=133
5B+8=133
5B=133-8
B=125/5
B=25
