the total cost of 2 kg of Apples in 6 of oranges is rupees 570 if the cost of 3 kg of apples is the same as the cost of 5 kg of oranges find the rate of cost of apples and oranges​

Respuesta :

Answer:

Cost of 1 kg apple = a = RS 102 (Approx.)

Cost of 1 kg orange = b = RS 61 (Approx.)

Step-by-step explanation:

Assume;

Cost of 1 kg apple = a

Cost of 1 kg orange = b

So,

2a + 6b = 570 ....... Eq1

and

3a = 5b..........Eq2

From eq 2

3a = 5b

a = 5b / 3

So,

2a + 6b = 570

2(5b/3) + 6b = 570

b = 61.07

Cost of 1 kg orange = b = RS 61 (Approx.)

a = 5b / 3

a = 5(61) / 3

Cost of 1 kg apple = a = RS 102 (Approx.)
