Answer :

Ratio of chromium and steel in first type stainless steel = 2:11


Ratio of chromium in first type stainless steel


Ratio of steel in first type stainless steel


Ratio of chromium and steel in second type stainless steel = 5:21


Ratio of chromium in second type stainless steel


Ratio of steel in second type stainless steel


Suppose kg of first type and y kg of second type stainless steel taken and mixed so that the ratio of measurement of Chromium and Steel becomes 7:32


Then, ratio of chromium in new mixture


Quantity of chromium in new mixture


Total quantity of new mixture = (x +y)


hence,





12x + 15 y = 14x + 14y


14x – 12x = 15y – 14y


2x = y



x: y = 1:2
