We have, R sits second to the left of P. Only two persons are sitting between P and N. From the above condition, there are two possibilities. Again we have, Only one person sits between N and M. M does not sit adjacent to P. The number of persons sits between P and M is the same as the number of persons sit between P and Q.
Again we have, The number of persons sits between R and N is one less than the number of persons sits between Q and M, when counted to the right of both R and M respectively M sits exactly in the middle of L and N. sits second to the right of L. From the above condition, case1 gets eliminated. Case 2 shows the final arrangement.
If tan θ = 4/3 and θ is an acute angle, find the value of sin θ + cos θ.
If (sinθ+cosθ)/(sinθ-cosθ) = 2, then the value of sin4 θ is
If tanθ = (2/√5), then find the value of cos2 θ
If sin x + cos x = √2 sin x, then the value of sin x - cos x is:
If 4cos2x - 3 = 0, and (0° > x > 90°), then find the value of 'x'.
Take θ = 450
If cos²α + cos²β = 2, then the value of tan⁴α + sin⁸β is
