उत्तर

i. School X: \[5p + 4q = 9500\] 

School Y: \[4p + 3q = 7370\] 

ii. Multiply the first equation by 3 and the second by 4:

\[15p + 12q = 28500\] 

\[16p + 12q = 29480\] 

Subtracting: \[p = 980\] 

Substituting: \[4q = 9500 - 4900 = 4600 \Rightarrow q = 1150\] 

Prize for hockey = ₹980. 

iiii. Cricket prize is higher by \[1150 - 980 = ₹170\] 

iv. Total prize for 2 students in each game: \[2 \times (980 + 1150) = ₹4260\]
