Mrs Andy baked some puffs. She gave
37 of the puffs to her cousin and
38 of the remainder to her auntie. Given that she gave 30 less puffs to her auntie than her cousin. How many puffs did
she bake at first?

Auntie |
Left |
|
| 6 u |
3 u |
5 u |
14 u |
Number of less puffs that Mrs Andy gave to her auntie than her cousin
= 6 u - 3 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Number of puffs that Mrs Andy baked at first
= 14 u
= 14 x 10
= 140
Answer(s): 140
