Try this option:
the rule: if f(-x)=f(x), then the function f(x) is even, if f(-x)=-f(x) then the function is odd.
1. f(x)=-5x⁴-2;
if to substitute x→(-x), then f(-x)=-5*(-x)⁴-2; ⇔ f(-x)=-5x⁴-2, in other words f(x)=f(-x), it means that this function is even.
2. f(x)=x³+2x.
if to substitute x→(-x), then f(-x)=(-x)³+2*(-x); ⇔ f(-x)=-(x³+2x), in other words f(-x)=-f(x), it means that this function is odd.

Price of chair is Rs 220 ( given)
1 chair = 220
3 chairs = ?
3 × 220
660 Rs
660 rs + 5 tables = 7540 rs
5 tables = 7540 - 660
5 tables = 6880
1 table = 6880/5
= 1376 rs
Price of 5 Table is 6880 and 1 table = 1376 rs
the answer is d I know this one
