Answer:
The answer is 1/2 which i think that's what you meant from C.
Step-by-step explanation:
A standard deck of cards has 52 cards. 13 of these cards are spades and 13 are diamonds.
A shopkeeper marks:
200*1.4=$280
With a discount of 25%:
$280*0.75=$210
30 pairs and a pair is 2 so 30*2 =60, so the answer is A
A:15
B: -15
C: 9
I hope this helps
