can you show me the working steps please
how can it be 20? If 20 patterned socks at first, that means there are 15 solid-coloured socks since the ratio is 3:4. Then it is not possible to throw away 16 solid-coloured socks. The right answer is 24.
1) Change the ratio of 3:4 to 9:12. This is because the difference between the two types of socks, before and after throwing away remains the same as for both types, an equal number of socks is thrown away. So before, 3:4. After, 1:4. Difference between 3 and 4 is 1. Difference between 1 and 4 is 3. Multiply before ratio by 3 to make difference same.
2) Now that the after ratio is 9:12, Now u can do the working and see that 8 units is 16. 1 unit is 2. 12 units is 24
