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

Mrs Goodsworthy has 6 gorgeous hats. 3 are green, 2 are blue, and 1 is canary yellow.

Four of her friends, Janet, Collette, Melanie, and Judith have come for tea and are trying on her hats. Mrs. Goodsworthy helps each friend put on a hat and has them stand in a line as shown below.

None of the ladies can see what color hat she is wearing.
Janet can see the colors of the hats Collette, Melanie, and Judith are wearing.
Collette can see the colors of the hats Melanie and Judith are wearing.
Melanie can see the color of the hat that Judith is wearing.
Judith cannot see the color of any of the hats.

Mrs. Goodsworthy asks her friends what color hat each of them is wearing, and Janet says she can't tell. Collette says she isn't able to tell either, and Melanie says she can't tell.

Judith, on the other hand, is able to announce the color of her hat. How was Judith able to figure out the color of her hat, and what was the color?

Let the acid and water is = x,y
If 1 litre of water added acid:water= x:(y+1)=20:80-->4x=y+1
If 1 litre of acid added their ratio is (x+1):y=1:3 --> 3x+3=y=4x-1--->x=4,y=15
Acid=4litres

20 years ago the age of Navya is 12 times more than Nitya. The present age of Navya is twice the age of Nitya. So what is the age of Nitya at present?

Explanation:- Let us assume Navya's present age is A
Nitya's present age is B
But now A = 2B -----> Equ1
Before 20 years back the ages are
A - 20 = 12(B - 20)
PUT A = 2B then
2B - 20 = 12B - 240
12B - 2B = -20 + 240
10B = 220
B = 22 years.

So present age of Navya is 22years.

JDear Admin
Kindly note that ín yeserday i. e on 14-2-17 puzzle answer was given as 1 54.5%.
In the solution you have wrongly calculated % profit.
It should be calculated on Cost Price which is 100.
Kindly note that %of profit or loss can be calculated on cost price only.
Why because cost price cannot be changed where as selling price can be changed.
Kindly note and rectify the answer.
