Greek is used as noun
Value of x is 100
Because 6250/10=625.
X/Y = 3/2 So X = 3Y/2
(X^2 + Y^2)/(X^2 - Y^2)
Now replace the X value from first equation
= [ (3Y/2)^2 + Y^2] / [ ((3Y/2)^2 - Y^2]
= [ (9Y^2/4) + Y^2] / [ (9Y^2/4) - Y^2]
= [ (9Y^2 + 4Y^2)/4] / [ (9Y^2 - 4Y^2)/4]
= (9Y^2 + 4Y^2) / (9Y^2 - 4Y^2)
= 13Y^2 / 5Y^2
= 13/5
By using Flip rule:
So,
A’s 1 day work = 1/10
B’s 1 day work = 1/15
(A+B)’s 1 day work =
(1/10+1/15)= (3 + 2)/30 = 5/30= 1/6
So together they can complete work in 6 days
