Answer: Second week
Step-by-step explanation:
Given
In first week, campers choose programmes in the ratio of [tex]7:5:8[/tex]
In second week, this ratio becomes [tex]7:6:4[/tex]
Suppose 100 campers Joined the camp
Number of hikers who choose camp craft in first week are
[tex]\Rightarrow \dfrac{7}{7+5+8}\times 100=\dfrac{7}{20}\times 100\\\\\Rightarrow 35[/tex]
Number of hikers who choose camp craft in second week are
[tex]\Rightarrow \dfrac{7}{7+6+4}\times 100=\dfrac{7}{17}\times 100\\\\\Rightarrow 41.17\approx 41[/tex]
Therefore, in second week more campers take part in camp craft.
If 100 campers take part then, 6 more campers takes part in camp craft.
