   10% less
   20% less
   30% less
   40% less
   50% less
   Option E

   Required percentage = (200 – 100)/200 * 100

   = 100/200 * 100 = 50% less

    

2. What is the ratio of the total number of pants sold in all the garments together to that of the total number of items sold in garment C?
   
   120: 70
   110: 70
