Answer:
Option a) 72
Step-by-step explanation:
Cost of Article = Rs. 75
Cost of Increase = 20% of 75
⇒ 20 / 100 * 75
⇒ 75 / 5 = Rs. 15
⇒ Increased Cost = 75 + 15 = 90
Hence new increased cost is Rs. 90.
Again 20% of the new price is reduced from new price.
⇒ 20% of 90
⇒ 20 / 100 * 90
⇒ 90 / 5 = 18
⇒ Reduced cost = 90 - 18 = 72
Hence the final reduced cost is Rs. 72
