Mrs Jenson baked some biscuits. She gave
25 of the biscuits to her nephew and
49 of the remainder to her father. Given that she gave 30 less biscuits to her father than her nephew. How many biscuits did
she bake at first?

|
| 6 u |
4 u |
5 u |
15 u |
Number of less biscuits that Mrs Jenson gave to her father than her nephew
= 6 u - 4 u
= 2 u
2 u = 30
1 u = 30 ÷ 2 = 15
Number of biscuits that Mrs Jenson baked at first
= 15 u
= 15 x 15
= 225
Answer(s): 225
