A worker was arranging some particular number of cylindrical aluminium soda cans in a square box but the box became full and there were 9 cans remaining to be put in. Then, he started arranging all Cans in a rectangular box where he could arrange 6 cans more along the length than the breadth after putting all the cans in the rectangular box. He found out that there was still space left for another 6 cans. What is the number of cans the worker had if it is known that the number of cans were More than 10 and no can was put on top of another can?

In this type of question we have to take LCM of the given digits.
So the LCM of 24,30,40&48 will be 2880
So all the wheels will come together again after 2880 Minutes i.e after 48 hours.

You have a block of platinum that can be exchanged in your bank either for cash
or for smaller blocks of platinum. If you exchange a block of m grams, you get
three blocks of weight m/2, m/3 and m/4 grams each. You don't get any fractional
part, as the division process rounds down the value. If you exchange the block of
platinum for cash, you get m units of currency. You can do any number of
exchanges for smaller blocks or currency.
Given the value of a block in grams as input, write a program that would print the
largest possible currency value that you can receive as the output. Assume that
the maximum value of a block that can be given as an input is 1,000,000,000
grams and the minimum value is 2 grams.
Sample input 1
12
Sample output 1
13
Explanation: You can change 12 into blocks

there are two mixtures of alcohol and water the quantity of alcohol in them being 25% and 75% of the mixture. if two gallons of first is mixed with 3 gallons of second, what will be the ratio of alcohol to waster in the new mixture?

Like? Yes (1) | No

Reply

Devendra Marghade 8 years ago

11/9

In 1st mixture: 25% alcohol, so 75% water, hence ratio of alcohol and water = 1/3
In 2nd mixture: 75% alcohol, so 25% water, hence ratio of alcohol and water = 3/1
In 2 gallons of 1st mixture, quantity of alcohol = 2x1/4=1/2 and water = 2x 3/4=3/2 gallons
In 3 gallons of 2nd mixture, quantity of alcohol =3x3/4=9/4 and water = 3x1/4=3/4 gallons
So in new mixture, alcohol =1/2 + 9/4 =11/4 and water=3/2 + 3/4 =9/4 gallons.
Hence ratio of alcohol and water = (11/4) / (9/4) = 11/9

A takes 15 steps for every 11 steps B takes.if one step of A is 3 Metres and that of B is 2.5 metres and B is 175 metres ahead of A,then what is the distance traveled by A to overtake B?
answer plz

Reply

Devendra Marghade 8 years ago

450 m.

15 step of A = 11 step of B
As 1 step of A is 3 m & B is 2.5 m, so (15x3) m or 45 m of A = (11x2.5) m or 27.5 m of B.
i.e when A and B are running in same direction,to cover relative difference of (45-27.5)m=17.5 m, A has to travel 45 m, so to cover 175 m, A will travel 175x45/17.5 m = 450 m.

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.

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?

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

Maths Quotes

Go down deep enough into anything and you will find mathematics.

Dean Schlicter

Pure mathematics is the world's best game. It is more absorbing than chess, more of a gamble than poker, and lasts longer than Monopoly. It's free. It can be played anywhere - Archimedes did it in a bathtub.
