ATQ, Marked price of mobile 'M' = 145% of 22,000 = (1.45) x 22,000 = Rs. 31,900 Selling price of mobile 'M' = 70% of 31,900 = (0.7) x 31,900 = Rs. 22,330 Profit earned on mobile 'M' = Rs. 22,330 - Rs. 22,000 = Rs. 330 Marked price of mobile 'N' = 155% of 28,000 = (1.55) x 28,000 = Rs. 43,400 Selling price of mobile 'N' = 118% of 28,000 = (1.18) x 28,000 = Rs. 33,040 Discount offered on mobile 'N' = (10,360/43,400) x 100 = 23.87% Statement (I) is false (the selling price of mobile 'M' is Rs. 22,330, not Rs. 23,100). Statement (II) is false (the discount on mobile 'N' is 23.87%, not 12%). Statement (III) is true (Rs. 5,040 profit on mobile 'N' is more than Rs. 330 on mobile 'M').
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:
