Mrs Xavier baked some biscuits. She gave
25 of the biscuits to her auntie and
49 of the remainder to her father. Given that she gave 16 less biscuits to her father than her auntie. How many biscuits did

| 6 u |
4 u |
5 u |
15 u |
Number of less biscuits that Mrs Xavier gave to her father than her auntie
= 6 u - 4 u
= 2 u
2 u = 16
1 u = 16 ÷ 2 = 8
Number of biscuits that Mrs Xavier baked at first
= 15 u
= 15 x 8
= 120
