- 152 |
| After |
1 u |
1 u + 264 |
(a)
After
Number of tarts that Gem had = 1 u
Number of tarts that Mrs Chan had = 5 x 1 u = 5 u
Before
Number of tarts that Gem baked = 1 u
Number of tarts that Mrs Chan baked = 1 u + 416
5 u = 1 u + 416 - 152
5 u - 1 u = 264
4 u = 264
1 u = 264 ÷ 4 = 66
Number of tarts that Gem baked
= 1 u
= 66
(b)
Number of tarts that Mrs Chan baked
= 1 u + 416
= 66 + 416
= 482
Answer(s): (a) 66; (b) 482
