Answer
4a + 6o = 620
8o = 5a
o = 5a / 8
4a + (5a / 8) *6 = 620
(37 a / 8) *6 = 620
37a / 8 = 620/ 6
37 a /8 = 310/3
a = (310*8) / 37*3
a = 22.34
o = 5 * 22.34/ 8
o = 13.9

Step-by-step explanation:
Given :
Cost of 4 kg of apples and 6 kg of oranges = rs 620
8o = 5kg of apples
o = 5a/8
4a + (5a/8)*6 = 620
(37a/8)*6 = 620
37a/8 = 620 / 6
37a/8 = 320 / 3
a = (310* 8)/ 37*3
a= 22.34
o= 5*22.34/8
o = 13.9
