The cost of an article was Rs.75. The cost was first increased by 20% ...
Initial Cost = Rs. 75
After 20% increase in the cost, it becomes,
(75 + 20% of 75) = Rs. 90
Now, Cost is decreased by 20%,
So cost will become, (90 - 20% of 90) = Rs. 72
So, present cost is Rs. 72
After 20% increase in the cost, it becomes,
(75 + 20% of 75) = Rs. 90
Now, Cost is decreased by 20%,
So cost will become, (90 - 20% of 90) = Rs. 72
So, present cost is Rs. 72

The cost of an article was Rs.75. The cost was first increased by 20% ...
Given:
The cost of the article = Rs. 75
The cost is increased by 20% and then reduced by 20%.
To find:
The present cost of the article.
Solution:
Let's solve this problem step by step.
Step 1: Increase the cost by 20%:
To increase the cost of the article by 20%, we can use the following formula:
Increased cost = original cost + (original cost * increase percentage)
In this case,
Original cost = Rs. 75
Increase percentage = 20%
Using the formula, we can calculate the increased cost:
Increased cost = 75 + (75 * 20/100)
= 75 + 15
= Rs. 90
Step 2: Reduce the cost by 20%:
To reduce the cost of the article by 20%, we can use the following formula:
Reduced cost = original cost - (original cost * reduction percentage)
In this case,
Original cost = Rs. 90
Reduction percentage = 20%
Using the formula, we can calculate the reduced cost:
Reduced cost = 90 - (90 * 20/100)
= 90 - 18
= Rs. 72
Therefore, the present cost of the article is Rs. 72.
Answer:
The present cost of the article is Rs. 72.
The cost of the article = Rs. 75
The cost is increased by 20% and then reduced by 20%.
To find:
The present cost of the article.
Solution:
Let's solve this problem step by step.
Step 1: Increase the cost by 20%:
To increase the cost of the article by 20%, we can use the following formula:
Increased cost = original cost + (original cost * increase percentage)
In this case,
Original cost = Rs. 75
Increase percentage = 20%
Using the formula, we can calculate the increased cost:
Increased cost = 75 + (75 * 20/100)
= 75 + 15
= Rs. 90
Step 2: Reduce the cost by 20%:
To reduce the cost of the article by 20%, we can use the following formula:
Reduced cost = original cost - (original cost * reduction percentage)
In this case,
Original cost = Rs. 90
Reduction percentage = 20%
Using the formula, we can calculate the reduced cost:
Reduced cost = 90 - (90 * 20/100)
= 90 - 18
= Rs. 72
Therefore, the present cost of the article is Rs. 72.
Answer:
The present cost of the article is Rs. 72.
