Explanation

Total candidates = 160  

Enrolled = 15% of 160 = 0.15 * 160 = 24

Not enrolled = Total - Enrolled  

= 160 - 24  

= 136

136 students were not enrolled.

Explanation

Selling price after discount = 80% of list price, because 100% - 20% = 80%.

Let list price = L.

So 0.8 * L = 480  

L = 480 / 0.8  

L = 600

The list price was Rs 600.

Explanation

Area of a triangle = 1/2 _ base _ height

Let old base = B, old height = H.  

Old area = 1/2 _ B _ H

New base = B + 25% of B = B + 0.25B = 1.25B  

New height = H - 20% of H = H - 0.20H = 0.80H

New area = 1/2 _ 1.25B _ 0.80H  

= 1/2 _ 1.00 _ B _ H  

= 1/2 _ B * H

New area = old area. It stays the same.

Explanation

If 15% discount was given, you paid 85% of the original price.

So 85% of Original = 8500  

0.85 × Original = 8500  

Original = 8500 ÷ 0.85 = 10,000
