L, N and T are partners sharing profits in the ratio of $5:3:2$. If N retires, what would be the gaining ratio of L & T?

The old profit-sharing ratio is $L:N:T=5:3:2$.When partner $N$ retires, and no explicit new sharing metrics or sacrifice deals are specified, the remaining partners $L$ and $T$ continue to gain and share in their relative old proportions.By striking out $N$ 's share ($3$), the relative ratio between $L$ and $T$ remains $5:2$. Therefore, the gaining ratio is $5:2$.
