Correct option is D
Given:
Gain = 5%
Loss = 5%
Difference in selling price = ₹5
Solution:
Let the Cost Price = ₹x
Selling Price at 5% gain = x + 5% of x = x +1005x = 100105x
Selling Price at 5% loss = x - 5% of x = x −1005x=10095x
Now, the difference in selling prices:
100105x−10095x=₹5
100105x−95x=5
10010x=5
10x=5
x = 50
Alternate Method:
2 → 5
1 → 2.5
Then,
20 ×2.5 = 50
