Method 1 Let the number be x Thus, 0*x/100=90 2x=90 x=45 40% of x =x*40/100 =45*2/5 =9*2 =18 Thus, 40% of the number is 18 Method 2 Let the number be x Thus, x00 is 40% of 5000 Steps to solve "00 is 40 percent of what number?" We have, 40% × x = 00;036 (A g /A c 1) x f ck /f y where A g is the gross area of the section and A c is the area of the core measured to the outside diameter of the helix Assuming 8 mm dia bars for the helix, Core diameter = 500 2 (40 8) = 436 mm A g /A C = 500/436 = 1315 036 (A g /A c 1) x f ck /f y = 036(0315) /250 = Volume of
