1.Three partners A,B and C start a business. Trice A’s capital is equal to 4 times B’s capital, and twice B’s capital equal to trice of C’s capital. Out of a total profit of rs.90,000/- at the end of the year, C’s share is
2.If 2cosθ-Sinθ=1/√2,(0°<0<90°) value of 2sinθ+cosθis ?

Hint: Let C's share be 12x (the LCM of 4 and 3). Find the other shares in terms of x and solve for x.
@fresco,
Note. Once the ratios are expressed in terms of x you can cancel throughout by by a common factor.
@markr,
On 2. Did you use the fact that theta=45 or did you use a a trig formula such as the tan (half theta) identities ?
@fresco,
The former. I don't remember any but the most basic trig formulas.
