Answer 1

Answer:

at 75000 rupees he bought the car

Answer 2

Answer:

cost price(CP)=x

sale price(SP)=3,00,000 - - - - - given

now

profit = SP - CP

so

profit = 3,00,000 - x

profit % = (profit / CP) * 100

25 = (3,00,000 - x / x) * 100

25/100 = 3,00,000 - x / x

(1/4) * x = 3,00,000 - x

x/4 = 3,00,000 - x

x = 4 * (3,00,000 - x)

x = 12,00,000 - 4x

x+4x = 12,00,000

5x = 12,00,000

x = 12,00,000/5

therefore

x = 2,40,000 = CP

hence his CP was 2,40,000.
