How many real solutions exist for the equation 3^x=2x+1?
4/√(3-x)) – √(3-x)
How many integral values for the set (x,y) would exist for the expression|x-4| + |y-2| = 5?
can someone explain how to visualize this problem graphically??
The work done by 4 men in 12 days is equal to the work done by 6 women in 10 days and is also equal to the work done by 8 children in 9 days. A man, a woman and a child working together take 10 days to complete a particular job. In how many days will the same job be completed by 2 women and 5 children working together?
p = (x + 3y + 5z){1/x + 1/3y + 1/5z}
if x + 6y = 6, for what value of z, P will be min?
a. 2/5
b. 1/5
c. 5/3
d. 3/5
PLEASE post the approach with your answer
x, y, z are integers.
x + y + z = 3. Then what should be the minimum value of (1/x) + (1/y) + (1/z)
Not sure about the options. Post the approach please

Can some one ls share the formula to find area of a closed figure ..which has some I and H in it..i am not able to recall it..
x is sitting 2 places left of y . Then no of people between them? 1 or 2
When they set question like - "for profit in long term" does it means , exhaustive set of events and their total expectation ?
A butler stole wine from a butt of cherry, which contained 60% of spirit solution.
He replaced wine containing only 10% spirit by volume. The resultant concentration of the mixture in the butt was then 25%.
What fraction of the butt of cherry did he steal ?
