Answer 1

Answer:18,200

Step-by-step explanation:

C.P of mobile=Rs.20,000(when Ravi bought it)

P%=30%(when he sold to Naveen at this profit)

S.P=100+30/100*20000=Rs.26000

C.P=Rs.26000

L%=30%

S.P=100-30/100*26000=18,200(sp odlf Ravi will be cp of gauri)

Answer 2

Gauri paid Rs. 18200 for the mobile.

Given : Ravi bought a mobile phone for 20,000.He sold it for a profit of 30% to Naveen. Naveen sold it at a loss of 30% to gauri.

To find : The amount that Gauri paid for the mobile.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the amount paid by Gauri)

So,

Ravi bought a mobile for = Rs. 20000

30% profit of Ravi = 20000 × 30% = 20000 × 30/100 = Rs. 6000

So,

Naveen bought the mobile at :

= Ravi's purchasing price + Ravi's 30% profit

= 20000 + 6000

= Rs. 26000

30% loss of Naveen = 26000 × 30% = 26000 × 30/100 = Rs. 7800

Now,

Gauri bought the mobile at :

= Naveen's purchasing price - Naveen's 30% loss

= 26000 - 7800

= Rs. 18200

(This will be considered as the final result.)

Hence, Gauri paid Rs. 18200 for the mobile.
