number of chairs :
2u + 147 ——- 7p

number of tables :
1u + 147 ——- 5p
2u + 294 ——- 10p

10p – 7p = 3p ——-294 – 147 = 147
1p ——- 147/3 = 49
5p ——- 5 x 49 = 245

Ans : 245 tables.

Units and parts method

Before

Chairs -> 2u

Tables -> 1u

After

Chairs -> 7p

Tables -> 5p

7p = 2u + 147

35p = 10u + 735

5p = 1u + 147

35p = 7u + 1029

10u + 735 = 7u + 1029

3u = 294

u = 98

Tables in the end -> 1u + 147 = 98 + 147 = 245
