Answer 1

Step-by-step explanation:

ANSWER

Cost of oranges and mangoes, each per kg=Rs.40

Amount paid daily for mangoes and oranges each =Rs.1200

⇒

40

1200

=30kg

Thus, the merchant got 30kg of oranges and mangoes each that day.

Let the price of mango be Rs.x next day.

⇒ Price of orange next day = Rs.(x+10

From the information given in the problem, we have

x

1200

−

x+10

1200

=20

⇒

x

60

−

x+10

60

=1

60x+600−60x=x(x−10)

⇒600=x

2

+10x

⇒x

2

+10x−600=0

⇒x

2

+30x−20x−600=0

⇒x(x+30)−20(x+30)=0

⇒(x+30)(x−20)=0

⇒x=−30,20

−30 is inadmissible , hence x=20

⇒x+10=20+10=30

Thus, price of oranges =Rs.30/kg on that day
