A.20N
B.15N
C.40N
D.30N

15 newton
since y axis represents the component along the y axis...
but if u want resultant of both then the answer will be
R = √(20)^2 + (15)^2 2(20)(15)cos90
R = √ 400+225
R = √625
resultant is 25 N
hope this helps u......

Bro we need to find y component of resultant NOT RESULTANT
You said about answer that it's 15N and at the same time you're calculating resultant=25N
ok wts d answer
yes answer is 15 N only
that was extra info
