avg cost of 5 pens + 4 pencils = 36
so , 9 = 36
1 = 4
so 25 pens = 25 * 4 = 100
25 pencils = 25 * 4 = 100

Avg cost of 5 pens and 4 pencils is Rs. 36
(5 pen + 4 pencils) 9=36
therefore 1 pen cost is 36/9=4, so 5 pen cost is 5x4=20 and 4 pencils cost is 4x4=16
Again, avg cost of 5 pens and 9 pencils is Rs.56
(5 pen + 9 pencils) 14=56
therefore 1 pen cost is 56/14=4, so 5 pen cost is 5x4=20 and 9 pencils cost is 9x4=36
So 25 pen cost is (25/a)=100 and 25 pencils cost is (25x4)=100
