Answer / hradayeshkumar sharma
If x is the total amount of work to be done, then
a does x/10 of work in one day while,
b does x/15 of work in one day
If y is the number of days that a and b have to work
together to finsh x amount of work then the equation becomes
(x/10)*y + (x/15)*y = x
which results into y = 6.

Answer / sri
THE ANS IS 6.
the problems of this kind are done using the formula
like if A can do a piece of work in n days then A's 1 day
work is 1/n. similar case with B let it be 1/m.
then to find out the work done by both A and B the no.of
days is to add (1/n + 1/m) by finding L.C.M, simplifying it
and reciprocal gives the no. of days.
here A's work is 1/10
B's work is 1/15
1/10 + 1/15 = 1/6 reciprocate this then the no .of days is 6.

Answer / gaurav goel
a finishes 1/10 work in a day when he does work alone...
b finishes 1/15 work in a day..
when they both work together means a+b...let they do 1/x
work per day when they work together....where x is the no.
so a+b=... or
1/10 + 1/15 = 1/x ,
(2+3)/30 = 1/x,
1/6 = 1/x,

A woman took a certain number of eggs to the market and sold some of them. The next day, through the industry of her hens, the number left over had been doubled, and she sold the same number as the previous day. On the third day the new remainder was tripled, and she sold the same number as before. On the fourth day the remainder was quadrupled, and her sales the same as before. On the fifth day what had been left over were quintupled, yet she sold exactly the same as on all the previous occasions and so disposed of her entire stock. What is the smallest number of eggs she could have taken to market the first day, and how many did she sell daily? Note that the answer is not zero.
