Answer 1

hi mate ...............

Answer 2

Answer:

Let the number of boys be “x” and no. of girls be “y”.

∴ x + y = 70 …… (i) [according to the given data in the question]

Total no. of oranges distributed = 180

Also,  

Each boy gets 2 oranges and each girl gets 3 oranges, so “x” boys will get “2x” oranges and “y” girls will get “3y” oranges in total. Therefore, we can write the equation as,

2x + 3y = 180 …… (ii)

Multiplying 2 throughout the eq. (i) and subtracting from eq. (ii), we get

2x + 3y = 180

2x + 2y = 140

-     -         -

---------------------

    y = 40

--------------------

Now, substituting the value of y in eq. (i)

⇒ x + 40 = 70

⇒ x = 30

Thus, number of boys is 30 and no. of girls is 40,
