Explanation

Simple interest for 1 year:

Principal = Rs. 50,000

Rate = 10% per year

Time = 1 year

Interest = Principal x Rate x Time / 100

= 50000 x 10 x 1 / 100

= Rs. 5,000

Total amount after 1 year = Principal + Interest

= 50,000 + 5,000

= Rs. 55,000

Explanation

Depreciation formula: 

Value after n years = Original Price x (1 - rate)^n

Given:

Original Price = Rs. 76000

Rate = 20% = 0.20 per year

Time = 2 years

Value after 2 years = 76000 x (1 - 0.20)^2

= 76000 x (0.80)^2

= 76000 x 0.64

= Rs. 48640
