Question

Write down the solution set of the in equation x <10
Let S= {x:x is a positive multiple of 3 less than 100}
P = {x:x is a prime number less than 20} then n (s) + n (p) is ?
- For a, b, c to be in G.P, the value of
a-b
is equals to
a-C
The value of Sin20° Sin40° Sin60° Sin80°?​

Answer 1

Answer:

S={x:x is a positive multiple of 3 less than 100}

⟹S={3,6,9,12,⋯,99}

⟹n(S)=33

P={x:x is a prime number less than 20}

⟹P={2,3,5,7,11,13,17,19}

⟹n(P)=8

n(S)+n(P)=33+8=41
