4% of x
20% of x = y 0.2x = y y% of 20 is y*20/100 = 0.2y = 0.2*0.2x = 0.04x y% of 20 is same as 4% of x
The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then what is the value of x ?
The sum of x% of y and y% of z is z% of x. x and y are integers such that 1 = < x = < 9, 1 = < z = < 9. If y is a perfect square number then how many ordered pair ( x , z ) are possible satisfying the given condition.
If x, y, z are 3 non zero positive integers such that x+y+z = 8 and xy+yz+zx = 20, then What would be minimum possible value of x*y^2*z^2
