From a deck of 52 cards, a card is drawn at random. If
P( A )= Probability that the card is black,
p( B )= Probability that the card is a diamond or a club and
p( C )= Probability that the card is a jack or a care of spade,
Then which of the following holds true?
Prob of Card is black=1/2
Probability that the card is a diamond or a club= ½
Probability that the card is a jack or a care of spade= 4/13
p (A) = p (B) > p(C)
45-4.5=40.5 are not rotten
CP = 45*60 = 2700
Profit = 10%
SP = (2700*110)/100 = 2970
Rs. 2970 is the selling price of 40.5 dozen oranges.
Price per orange = 297040.5∗12 = Rs. 6.1
Rs. 6.1 gives a profit of 10% so Rs. 6.5 will give a profit of more than 10% and this satisfies the given condition.
5!-4!*2!=72

let each side of triangle is xkm,
and the avg speed =ykmph
so,x/300+x/200+x/240=3x/y
=>(4x+6x+5x)/1200=3x/y
=>y=(1200*3)/15=240kmph
4*4*3*2*1 = 96 (without repetition)
