Since the impurity in the solution reduces to factor = 1/6 : the quantity of solution should increase to 6 times its original value Applying the above logic - we have the new quantity as 30 x 6 = 180 Quantity of pure petrol added = 180 -30 = 150 Remember - we are not changing the quantity of impurit...
if (m-4) is 7 more than n, m is 11 more than n.jayanti wrote:If m - 4 is 7 more than n, then m + 9 is how much more than n + 2?
