Total cost price = (10 * 400) + (15 * 300) = 4000 + 4500 = ₹8500. Total selling price = (10 * 600) + (15 * 500) = 6000 + 7500 = ₹13500. Total profit = 13500 - 8500 = ₹5000. Correct answer: D) ₹5,000
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:
