Let the sum of the first ‘m’ terms of an Arithmetic Progression be Sm and ‘n’ terms be Sn. if the first term and common difference are 2 and 5, respectively, then find the ratio of Sm and Sn.

• A. (m(5m - 1))/(3n(5n - 1))
• B. (m(5m - 1))/(2n(5n - 1))
• C. (2m(5m - 1))/(n(5n - 1))
• D. (m(5m - 1))/(n(5n - 1))
