Question

The cost of an article was Rs.75. The cost was first increased by 20% and later on it was reduced by 20%. The present cost of the article is:
A.Rs. 72
B.Rs. 60
C.Rs. 75
D.Rs. 76

Answer 1

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

Answer 2

20%of 75 is 15

new price is 75+15 = 90

20%of 90 is 18 (reduced)

90-18=₹72
