k+17 is the right option.
Let A,B,C,D........Stands for 1,2,3,4......
Then the terms are multiples of 7
Hence k+ 17 is the correct answer.

Dear Users,

There was a error in today's puzzle of 24th March 2017. The statement in question should have been:
What is the probability that India doesn't wins the match? instead what got published was
What is the probability that India wins the match?

We are giving 20 marks to everyone who attempted the question.
We will also updated the question and answer with appropriate explanation.

G.S.Kantharao 7 years AGO

Dear Admin
Please check the answer given today which is for yesterday's question. In the question it was asked winning probability. In the answer it was given loosing probability.
... Possible outcomes are=6C1*6C1 - 10= 26 Here (4,1)(4,2)(4,3)(4,4)(4,6)(6,1)(6,2)(6,3)(6,4)(6,5) are not the outcomes why becaz if first ball is played the winning shot they need not play the next one.
Hence they are 26
Probability for winning is 16/26= 8/13 which was not given.

I agree with you but do not agree on ignoring 10 outcomes - if 4 or more runs are scored in 1st ball then 2nd ball outcome is not relevant but that doesn't imply that these 10 outcomes are not part of possible outcomes.

If 12 candies is sold for tk 10 then there is a loss of x%. If 10 candies is sold for tk 12 then there is a profit of x%. What is the value of x?
Pls help me to solve

Like? Yes | No

Reply

~Sandeep~ 7 years ago

Let the CP of 12 candles be P

When sold for 10:
Loss % = x = (P-10)*100/P ---(i)

When sold for 12:
Profit % = x = (12-P)*100/P ---(ii)

Equating (i) and (ii)

P-10 = 12-P
=> 2P = 22
P = 11

So x = (P-10)*100/P = (11-10)*100/11 = 100/11

total 13 marbles so n(s) =number of ways drawing 3 marbles out of 13= 13c3=286 let E be the event of drawing 3 balls same colour E=3 balls of 4 green and 3balls out of 5 yellow and 3 balls out of 4 white
so n(E)=4c3+5c3+4c3= 4+10+4= 18 P(E)=n(E)/n(S)=18/286= 9/143
Required probability =1-9/143=136/143 is answerr bro here formula for combination is ncr=n!/r! (n-r)! if 5! means 5*4*3*2*1 like 5c3 means n=5 and r=3 if any doubs again message me
