Let breadth be x then length=4x
So area = 4x2 = 2500 => x = 25 and hence length = 4(25) = 100
Let atul sold it in Rs x Now that will be CP for irfan and hence
495000 = 90/100(x) => x= 550000
So profit % to atul = 100000/450000 * 100 = 22.22%
If marked price=x, cost price=CP . As 5x/7 is 115 of CP, so x will be x*115/(5x/7)of CP=161 of CP % Profit earned ,if sold at marked price=61
let total distance is x
x-(4/5x+3/20x)=1
x-[(16+3)/20]=1
1/20x=1
X=20Km
Let a=4.56, b=5.44
We know a3+b3=( a+b)(a2-ab+b2)
(4.56+5.44)(4.562-4.56*5.44+5.442)/ (4.562-4.56*5.44+5.442)
4.56+5.44
