Ratio of Profit of A and B = 2 : 1 Ratio of Profit of C and D = 2 : 1 Given that, total investment of A and B was 25% less than that of C and D Ratio of investment of A, B and C, D = 3 : 4 Total profit of all four persons = 10500 Investment of A and B = 3/7 × 10500 = Rs. 4500 Profit of A = 4500 × 2/3 = Rs. 3000
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:
