Total unit of food = 200*31=6200
In 27 days total consumption = 27*200 = 5400
Total food left = 6200-5400= 800 units
Soldiers left = 80
So food will last for 800/80= 10 more days

thanks bhai...

A fort has sufficient food for 200 soilders for 31 days. After 27 days 120 soilder left . for how many xtra days will rest of the food last for remainig soilders???

===================================================

is it 31 extra men to be hired.

Nahi bahi answer is 60

Bhai...one more question:

An enginer undertakes a project to build a road 15km long in 300 days and employs 45 men. After 100 days he finds only 2.5km of the road completed .Find the number of extra men he must employ to finish the work..

54/81 = X days /12
so x = 8 days .. which is no of days taken by B alone

so together they will finish in

1/8+1/12= 1/t

t = 4.8 days ??

Bhai ...correct answer...Thankss

A can do a peice of work in 12 days . A and B complet the work together and were paid Rs54 and rs81 respectively . How many days they must have taken to complete the work together?

A can do a peice of work in 10 days and B in 12 days .find how much time will they take to complet the work under folowing cicumstances:
1. Working alternalty start with A.
2. Working alternalty start with B
3. If B leaves 2 days before the actual completeioon of work
4. If B leaves 2 days before the scheduled completion of work....


Give answer with xplaintion. Nt abe to understnd the concept.

if the inverse function of f=ax+b if f^-1=bx+a then the values of a and b are
a 1,1
b.-1,1
c.1,-1
d.-1,-1

Bhaiii log....Kitthe gaye wana solution of this:sneaky:

if the inverse function of f=ax+b if f^-1=bx+a then the values of a and b are
a 1,1
b.-1,1
c.1,-1
d.-1,-1

if f be a function with domain 0<=x<=1

defined as f = 2x if 0<=x<=1/2
-2x+2 if 1/2<=x<=1

find the area between the curve y=f(f(f(x)) and the coordinate xsis...
