When a number Y is divided by X  it leaves a remainder of 11.
When Y is divided by 8X , the remainder is 92.
What is the remainder when Y is divided by 4X ?
The method is too clumsy to be worth noting.
However 308/(8*27) = 1*216+92, while 308/27 = 11*27+11.
If x=27, y=308, then y/(4x) = 77/27 =2*108+92/108, so the answer is 92.
