Question

by selling a car for ₹3, 00,000 a dealer makes a profit of 25% . at what price did the dealer bought the car​

Answer 1

Answer:

selling price(s.p.) = 3,00,000

profit % = 25 %

now

if

for 100 rs he`s getting 125 rs.(25% profit)

then for 3,00,000 rs what may the cost price?

we `ll put in following way

100 - 125 then

x- 3,00,000

so 100*3,00,000/125 = 2,40,000 will be the cost price of that car.

or

let`s put it another way

consider

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

Answer 2

Answer:

Step-by-step explanation:

s.p. = 3,00,000

profit % = 25 %

now ,

if

for 100 rs he`s getting 125 rs.(25% profit)

then for 3,00,000 rs what may the cost price?

we `ll put in following way

100 - 125 then

x- 3,00,000

or

let`s put it another way

consider

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.
