Cost price of 3 dozen momos = Rs. 162 Selling price of 30 momos = 30 × (64.8/12) = Rs. 162 Selling price of 6 momos = 6 × (48.6/12) = Rs. 24.3 Selling price of 36 momos = 162 + 24.3 = Rs. 186.3 Profit earned on selling 36 momos = 186.3 – 162 = Rs. 24.3 Profit percentage = (24.3/162) × 100 = 15%
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:
