Mrs Billy baked some tarts. She gave
35 of the tarts to her buddy and
34 of the remainder to her niece. Given that she gave 12 less tarts to her niece than her buddy. How many tarts did
she bake at first?

Niece |
Left |
|
| 6 u |
3 u |
1 u |
10 u |
Number of less tarts that Mrs Billy gave to her niece than her buddy
= 6 u - 3 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of tarts that Mrs Billy baked at first
= 10 u
= 10 x 4
= 40
Answer(s): 40
