Let N = cost of 1 notebook ; M = cost of 1 marker..

Given, 5N + 3M <= 10 question is 4N + 4M <= 10 ???

1.) N < 1

Let N = 0.2
=> 5N = 1
=> 3M <= 9
=> M <= 3
10\$ can be sufficient or can not be sufficient.. hence, insufficient

2.) 11N <= 10
=> N <= 10/11
Maximum value of N = 10/11
=> 3M <= 10 - 50/11
=> Maximum value of M = 20/11
When N = 10/11 and M = 20/11 then, 4N + 4M > = 10
When N = 0.2 and M = 1 then 4N + 4M <= 10 hence, insufficient..

Combining both,,insufficient..Hence, E
