Through this point draw a dotted line curve parallel to the neighboring curve. Now draw a strength line from the desired strength on y-axis, where this line cuts the curve, draw a perpendicul x-axis which will give w/c ratio for the targeted strength i.e., 45 MPa. From this curve for 45 MPa strength the water/cement ratio comes out 0.54.
