Question
A shopkeeper sold an article after giving a discount of
23% and made a profit of Rs.26. Find the difference between the marked price and selling price of the article if cost price of the article is Rs.590.Solution
Selling price of the article = 590 + 26 = Rs.616 Marked price of the article = 616/0.77 = Rs.800 Required difference = 800 – 616 = Rs.184
The value of sec2 45˚ + 2 tan 135˚ is –
Evaluate the following:
sin 60° × cos 30° − sin 30° × cos 60°
Evaluate the following:
sin 25° × cos 65° + sin 65° × cos 25°
If sec²x + csc²x = 10, find the value of tan²x + cot²x.
Solve for 0° ≤ θ ≤ 360°:
2 sin²θ + 3 sinθ − 2 = 0
- If (tan 6a · tan 3a = 1), then find the value of (tan 9a).
If cot A = √3, then what will be the value of sin4 A?
If 2 sec 3x = 4, then the value of x:
