% Discount in getting free items (a) = (free items/ total items) x 100 = [5/(5+15)] x 100 = 25% Next % discount (b) = 20 So net discount(%) = a+b -(ab/100) = 25 + 20 - (25 x 20)/100 = 40% CP MRP (100 - D) (100 + P%) (100 - 40) : (100+20) 6 0 : 120 1 : 2
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:
