There r some chickens and some chicken field.If we sell 75 chickens Then the feed will last 20 days longer.If we buy 100 chickens more, then the feed will get over before 15 days.What is the present number of chickens?

no of chickens x?is inversely proportional to the no of days y. therefore,

x=k/y.........(a)?? now consider the first condition

x-75=k/(y+20)??,? k=(x-75)(y+20).............(b)? solve (a) and (b) and get the eq for k in terms of y

x+100=k/(y-15)?,? k=(x+100)(y-15)...........(c ) solve (a) and (c) and get the eq for k in terms of y

equating these two equations in terms of y we can get the value of y

y=60?? , k= 75*60*4? , x=75*4

.A man is visited by his 7 friends in the following pattern.The first friend visited every day.The second visited every second day.The third visited every third day and so on upto 7th friend on every 7th day.When will they all meet together?

?this we can find using LCM of 1,2,3,4,5,6,7 that is 420. they will meet on 420th day

Mr. X (who got the Param veer charka in 1948), died at the age which is 1 / 39th of his year of birth, in which year did he born.

year of born consider x

the eqn is 1948-x=x/39

x is approximately 1899

For 1st question answer may be 40.
A & B starts with 40 marbles.
In first run, A wins 20 means total at A=60 & that of B=20.
Then A looses (2/3)rd means now total at A=20 & B=60.
