Let the SP of sofa be Rs. x which is given to Sujit. x * (92/100 * 88/100 – 80/100) = 300 x * 0.0096 = 300 x = 31250 Now Sujit purchased for 31250 * 92/100 * 88/100 = 25300 Deepak purchased sopha = 12500 * 88/100 + 500 = 11000 + 500 = 11500 Profit% = (25300 – 11500) x 100/11500 = 120%
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:
