Answer 2

Answer:

the cost of chiken (x) = Rs 300

the cost of mutton (y)= Rs 1200.

Step-by-step explanation:

Let x be the cost of chiken and y be the mutton

According to the question.

4x + 5y = 7200.....(1)

4x = y.........(2)

Now, substitution equation (2)in (1) we get,

4x + 5(4x) = 7200

or, 4x +20x =7200

or, 24x = 7200

or, x = 7200\24

or, x = Rs. 300

Again,

put the value of x in equation (2) we get,

4 ×300 = y [;.x = 300]

Rs 1200 = y

thus, the cost of chiken (x) = Rs 300

the cost of mutton (y)= Rs 1200.
