Answer 1

Step-by-step explanation:

Let the no. of oranges =x= no. of bananas

cost price =5x+2x=7x

Gain on oranges =

100

20

×5x=x

Gain on Bananas =

100

15

×2x=0.3x

Profit ⇒1.3x=390

⇒x=

1.3

390

=300

No. of oranges purchased =300.

Answer 2

Answer:

Step-by-step explanation:

Let the no. of mangoes and oranges be x

Cp of x mangoes = Rs 10x

Cp of x oranges = Rs 5x

Profit on mangoes = 15*10x/100 = 150x/100 = 3x/2

Profit on oranges = 30*5x/100 = 150x/100 = 3x/2

Now , total profit = 3x/2 + 3x/2 = 540

6x/2=540 = 3x =540

x=540/3= 180

There are 180 mangoes and 180 oranges.
