certain stocks in january were 40 % less than they were in february and 15 % greater than they were in march . what was the percentage decrease in the stocks from february to march ?
"let stocks value in feb = 100 = > in jan = 60 and march = 60 * 100 / 115 = 51.2 % thus , percent decrease in stocks from feb to march = 100 - 51.2 = 48.8 % hence answer is d"
