Answer:
There are 42 red colour socks and 44 green color socks
Step-by-step explanation:
Let there are r red socks and g green socks.
ATQ,
He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks.
4g-3r=50 ....(1)
Half the number of green socks plus one-third of the number of red socks is 36.
![\dfrac{g}{2}+\dfrac{r}{3}=36\\\\3g+2r=216\ .....(2)](https://tex.z-dn.net/?f=%5Cdfrac%7Bg%7D%7B2%7D%2B%5Cdfrac%7Br%7D%7B3%7D%3D36%5C%5C%5C%5C3g%2B2r%3D216%5C%20.....%282%29)
Multiply equation (1) by 2 and equation (2) by 3.
8g-6r = 100 ....(3)
9g +6r = 648 ....(4)
Add equation (3) and (4)
8g-6r + 9g +6r = 100+648
17g = 748
g = 44
Put the value of g in equation (1).
4(44)-3r=50
176-3r = 50
176-50 = 3r
r = 42
Hence, there are 42 red colour socks and 44 green color socks.
