18) Solution

बहुलक = 3 माध्यिका -2 माध्य
बहुलक = माध्यिका + 2 माध्यिका - 2 माध्य
बहुलक - माध्यिका = 2 माध्यिका - 2 माध्य
बहुलक - माध्यिका = 2 ( माध्यिका - माध्य )
12 = 2 ( माध्यिका - माध्य )
माध्यिका - माध्य = 12/2
माध्यिका - माध्य = 6 (answer)

19) Solution By option (A) 90°

4 sin2Q - sinQ + 1 = 0
4 sin2(90°) - sin(90°) + 1 = 0
4 sin(180°) - sin(90°) + 1 = 0

चुकी sin180°=0 and sin90°=1

4(0) - 1 + 1 = 0
0 = 0
LHS = RHS

Answer> option number (A) 90°
