Answer 2

The price of apples decreased by 10 rupees per kg.

Step-by-step explanation:

Let x be the initial price of apples/kg.

Number of apples = $\dfrac{240}{x}$

The price of apples decreased by 25%. So, new price per kg is

$x-\dfrac{25}{100}x=x-0.25x=0.75x$

Number of apples = $\dfrac{240}{0.75x}$

It is given that if price of apples decreased by 25%, then he can take 2 kg extra in ₹240.

$\dfrac{240}{0.75x}-\dfrac{240}{x}=2$

Multiply both sides by 0.75x.

$240-180=1.5x$

$60=1.5x$

Divide both sides by 1.5.

$40=x$

The initial price of apples is 40/kg.

Decreased amount is 25% of 40.

$40\times \frac{25}{100}=10$

Therefore, the price of apples decreased by 10 rupees per kg.
