1 u + 371 |

- 181 |
| After |
1 u |
1 u + 190 |
(a)
After
Number of scones that Gem had = 1 u
Number of scones that Mrs Koh had = 3 x 1 u = 3 u
Before
Number of scones that Gem baked = 1 u
Number of scones that Mrs Koh baked = 1 u + 371
3 u = 1 u + 371 - 181
3 u - 1 u = 190
2 u = 190
1 u = 190 ÷ 2 = 95
Number of scones that Gem baked
= 1 u
= 95
(b)
Number of scones that Mrs Koh baked
= 1 u + 371
= 95 + 371
= 466
Answer(s): (a) 95; (b) 466
