x varies inversely as square of y. given that y = 3 for x = 1. the value of x for y = 7 will be equal to:
divide(multiply(1, power(3, const_2)), power(7, const_2))
explanation : solution : given x = k / y ^ 2 , where k is constant . now , y = 3 and x = 1 gives k = 9 . . ' . x = 9 / y ^ 2 = > x = 9 / 7 ^ 2 = 9 / 49 answer : e
