Identify difference between tables and chairs did not change because same no. of tables and chairs are added. Make their difference before and after 2u (only after detailing basic info in table below).
Chairs | Tables | Total | |
At first ratio | 2 (#4a. 4u) | 1 (#4b. 2u) | 1 (#2. make 2u) |
Change no. | +147 (#5a. Deduce +3u) | +147 (#5a. +3u) | |
End ratio | 7 (#3a. 7u) | 5 (#3b. 5u) | 2 (#1. keep 2u) |
(Q: end no.?) | Follow steps# |
3u —> 147
1u —> 49
Tables at the end is 5u —> 245#
chairs :
2u + 147 ——– 7p
tables :
1u + 147 ——- 5p
2u + 294 ——- 10p
10p – 7p = 3p ——- 294 – 147 = 147
1p ——- 147/3 = 49
5p ——- 49 x 5 = 245
Ans : 245 tables.
