Answer 1

Answer:

10 percent

Step-by-step explanation:

After a discount of 20%

After a discount of 20%cost of the ring = 80% of Rs.150

After a discount of 20%cost of the ring = 80% of Rs.150 = 150×80/100

After a discount of 20%cost of the ring = 80% of Rs.150 = 150×80/100 = Rs.120

After a discount of 20%cost of the ring = 80% of Rs.150 = 150×80/100 = Rs.120Let the additional discount be x%

After a discount of 20%cost of the ring = 80% of Rs.150 = 150×80/100 = Rs.120Let the additional discount be x%120 - 108 = Rs.12

After a discount of 20%cost of the ring = 80% of Rs.150 = 150×80/100 = Rs.120Let the additional discount be x%120 - 108 = Rs.12, x% of 120 = 12

After a discount of 20%cost of the ring = 80% of Rs.150 = 150×80/100 = Rs.120Let the additional discount be x%120 - 108 = Rs.12, x% of 120 = 12= 120×x/100 = 12

After a discount of 20%cost of the ring = 80% of Rs.150 = 150×80/100 = Rs.120Let the additional discount be x%120 - 108 = Rs.12, x% of 120 = 12= 120×x/100 = 12= x = 12×100/120 = 10%
