an ant smartly moves across a staircase taking the shortest distance. calculate the distance it takes to reach top to B from A given that staircase consist of 2 steps. it also known that the length,breadth and height is 6cm,2cm and 1cm respectively

Reply Like? Yes (2) | No

~Sandeep~ 7 years ago

Shortest distance would be when ant doesn't travel any distance in the direction of length while climbing the height or passing the breadth.
So for one stair the smart Ant should cover = Height of Stair+ Breadth of stair = 1+2 =3 cm

So for 2 stairs the shortest distance traveled by Ant = 2*3= 6 cm

Ant will move diagonally on each step covering a distance of sqrt 5 cms.
Hence total distance travelled for two steps = 2*sqrt 5 cms.

Like? Yes (3) | No (1)

raushan kumar 6 years ago

Assume there is a staircase with 2 steps length = 6cm and breadth and height are 1 and 2
so the shortest distance is from left end of the 1st step to right end of the 2nd step which forms a right angled triangle, triangle side are AB, AC and BC.
By using pythagoras theorem,
AC^2 = AB^2+BC^2
AC^2 = 6^2+(2+1+2+1)^2 [height + breath of 2 steps]
AC^2 = 36+36
AC = 6 _/ 2

1/7
Any number N, when divided by 7, could have remainder as {0,1,2,3,4,5,6}
So total number of possible outcomes = 7

1992 Feb have 5 Sundays. In which year, the month Feb have 5 Sundays next?

Reply Like? Yes | No

Varun 7 years ago

2020 will have the next,

For every 4 years( between 2 leap years), there will 365*4+1 days
= 1456 days
= 1461+5 days
= 208 weeks + 5 days
= 208 negligible weekdays count + 5 to be considered odd days.

So, 1996 Feb will have 5 Fridays ( because Sunday + 5th odd day = Friday)

So, for every 4 years, if we get 5 odd days.
then to get 7 or multiple of 7 as odd day,
we should go on searching in multiples of 5(required) days,
i.e. in 5,10,15,20,25,30,35,40,45,....
35 is the nearest multiple of both 5,7 which is nothing but LCM(least common multiple)

So to get 35 odd days, we are taking 7 leap years to pass out = 7*4years = 28 years
= 1992 + 28 = 2020

You can cross check it with real calendar, both 1992 and 2020 have 5 Saturdays(respectively)

Short cut, easy, handy method is to find odd days in these kind of questions and use logic accordingly.
