1. purchase price
2.its value after 1 year​

Answer 1

Step-by-step explanation:

• Present value of car = 252480rs
• He purchased car 2 year ago
• depreciates of car per year at rate = 20%
• We have to find Purchase price
• also Value of car after 1 year

Solution:-

Actual price before 2 year is 40% greater than present price of car

thus present value of car is only 60% of original no

$60\%ofx = 252480 \\ \frac{60 \times x}{100} = 252480 \\ x = \frac{252480 \times 100}{60} \\ 420800 \: is \: original \: price \:$

(ii) value of car after 1 year on present value

$\frac{252480 \times 20}{100} = 50496 \\ 252480 - 50496 = 201984$
