Mrs Eric baked some biscuits. She gave
37 of the biscuits to her father and
38 of the remainder to her auntie. Given that she gave 21 less biscuits to her auntie than her father. How many biscuits did

| 6 u |
3 u |
5 u |
14 u |
Number of less biscuits that Mrs Eric gave to her auntie than her father
= 6 u - 3 u
= 3 u
3 u = 21
1 u = 21 ÷ 3 = 7
Number of biscuits that Mrs Eric baked at first
= 14 u
= 14 x 7
= 98
Answer(s): 98
