Keith_Richards [23]

Answer: $33.33\%$

Step-by-step explanation:

Given

Raju buy an old car for $Rs\ 1,25,000$

He spent $Rs\ 25000$ on its repair

The selling price of the car $Rs\ 2,00,000$

So, the cost price is

$\Rightarrow C.P.=1,25,000+25,000=Rs\ 1,50,000$

Here, $S.P.> C.P.\quad \text{i.e. gain}$

Gain percent is

$\Rightarrow \text{Gain percent}=\dfrac{2,00,000-1,50,000}{1,50,000}\times 100=\dfrac{50,000}{1,50,000}\times 100\\\Rightarrow \text{Gain percent}=33.33\ \%$
