A player holds 15 cards of four suits, of which eight are red and seven are black. The number of diamonds is twice the number of spades, and the number of hearts is equal to the number of diamonds. How many clubs does he hold?
5
2
3
4
Correct answer
5
Why this answer is correct
Given:
Total cards = 15
Red cards (hearts + diamonds) = 8
Black cards (spades + clubs) = 7
Number of diamonds = 2 × number of spades
Number of hearts = number of diamonds
Formula used:
Let D = diamonds, H = hearts, S = spades, C = clubs
We have:
D + H + S + C = 15
H + D = 8
S + C = 7
D = 2S
H = D
Calculation:
H = D ⇒ red cards: H + D = D + D = 2D = 8 ⇒ D = 4 ⇒ H = 4
D = 2S ⇒ 4 = 2S ⇒ S = 2
S + C = 7 ⇒ 2 + C = 7 ⇒ C = 5
∴ The player holds 5 clubs.
