Mrs Sam baked some tarts. She gave
47 of the tarts to her niece and
49 of the remainder to her father. Given that she gave 40 less tarts to her father than her niece. How many tarts did
she bake at first?
| Niece |
Remainder |
Total |
| 4x3 |
3x3 |
7x3 |
| |
Father |
Left |
|
| 12 u |
4 u |
5 u |
21 u |
Number of less tarts that Mrs Sam gave to her father than her niece
= 12 u - 4 u
= 8 u
8 u = 40
1 u = 40 ÷ 8 = 5
Number of tarts that Mrs Sam baked at first
= 21 u
= 21 x 5
= 105
Answer(s): 105
