Question

If the cost of banana is increased by Rs 2 per dozen,one can get one dozen less Bananas for Rs 840. Find the original cost of one dozen Bananas ​

Answer 1

Answer:

Rs 40

Step-by-step explanation:

let the original cost of bananas per dogen be x.

new price: (x+2)

according to the question,

$\frac{840}{x} - \frac{840}{x + 2} = 1$

this gives,

x = 40, and some negative value.

so, original price = Rs 40 per dogen.
