Let $\displaystyle s_1, s_2, s_3, \ldots ., s_{10}$ respectively be the sum to $\displaystyle 12$ terms of $\displaystyle 10$ A.P. s whose first terms are $\displaystyle 1,2,3, \ldots . ., 10$ and the common differences are $\displaystyle 1,3,5, \ldots \ldots, 19$ respectively. Then $\displaystyle \sum_{i=1}^{10} s_i$ is equal to
