Answer 2

The percentage decrease in cost is 10.5%

Given:

Cost of a bike last year was Rs 19000.

The cost of the bike this year is Rs 17000

To find:

The percentage decrease in cost.

Solution:

Step 1 of 2:

Cost of a bike last year was Rs 19000.

The cost of the bike this year is Rs 17000

Decrease value = 19000 - 17000

Decrease value = 2000

We can calculate the decrease percentage by using the following formula,

Decrease % = ( Decrease value) / ( Original value ) × 100

Step 2 of 2:

Decrease value = 2000

Original value = 19000

Decrease % = ( Decrease value) / ( Original value ) × 100

Decrease % = $\frac{2000}{19000}$ × 100

Decrease % = $\frac{2000}{190}$

Decrease % = 10.5%

The percentage decrease in cost is 10.5%
