Question
A man sells two pipes at 12 each. He gains 20% on one
and loses 20% on the other. In the whole transaction, there isSolution
We know that overall loss% = 4% {by 20 – 20 – (20 × 20)/100 = - 4%} 4% = 1/25 25 is CP so SP = 24 Therefore, loss of Rs. 1 will incurred in overall transaction.

If cos1.5B = sin(B + 5°), then find the measure of 'B'.
If sec a + tan a = 5/2, find the value of sin a.Â
- Simplify the following trigonometric expression:
9 sin 36° csc 54° − 7 tan 47° cot 43° if 8 sin 2 x + 3 cos 2 x = 4  then find tan x
If sin (2x + 50) o = cos (2y - 50) o, such that, 0o < x + y < 90o, then find the value of tan(x + y) .
Find the value of the given trigonometric expression:
(sin 25°cos 65° + cos²25°) × sin 30° + (cos 60°tan 45°) × sec 60°
...

The Value of (sin38Ëš)/(cos52Ëš)+ (cos12Ëš)/(sin78Ëš)- 4cos²60Ëš is
