From (iii), we will have two cases: Case 1. If the one who like Maaza sits at place no.1, then the one who likes Pepsi sits at place no.5. A will sit at place no. 4. From (ii), the one who likes Sprite sits at place no.2. From (i), C sits at place no.1. E and the one who like Miranda sit at place no. 4 and 6 respectively. D will sit at place no. 2. B will sit at place no. 5. Only person left for place no. 3 is F, who likes Coca-Cola. Case 2. If the one who like Maaza sits at place no.2, then the one who likes Pepsi sits at place no. 4. A will sit at place no. 5. From (ii), the one who likes Sprite sits at place no.1. From (i), C sits at place no.2. E and the one who like Mirinda sit at place no. 3 and 5 respectively. B and the one who likes Coca-Cola sit at place no. 4 and 6 respectively. This case will get discarded as F does not like Sprite.
Final arrangement as shown below:
sin2 9 ° + sin2 10 ° + sin2 11 ° + sin2 12 ° + ……… + sin2 81 ° = ?
...If 4cos2x - 3 = 0, and (0° > x > 90°), then find the value of 'x'.
If tan θ = (2/√5), then determine the value of cos2 θ
If √3cosec 2x = 2, then the value of x:
If x = (sin 30 ° + cos 30 ° )/sec 60 ° , then find the value of 4x.
If sin3A = cos(5A-30°), then what is the value of A? Given that 3A is an acute angle.
If sin x + cos x = √2 sin x, then the value of sin x - cos x is:
Simplify the given equation:
