Question
A and B started a business by investing Rs.4000 and
Rs.7000 respectively. After 6 months A withdrew 50% of his investment. If at the end of the year, profit share of B is Rs.8400, then find the profit share of A.Solution
Profit sharing ratio A and B = 4000 x 6 + 2000 x 6 : 7000 x 12 = 3:7 So, profit share of A = 8400 x (3/7) = Rs.3600
Find the value of sin(θ) if 2sinθ = tanθ, for 0 < θ < 90°.
The value of (3tan10°-tan³10°)/(1-3tan²10°) is equal to
- Find the value of sin²18° + sin²72° + cos²63° + cos²27°.
- Find the maximum value of (15sin A + 12cos A).
∆ PQR is right-angled at Q. If ∠R = 60º, then find the value of cosec P.
If cosec2A = (sin60o + tan45o X sec245o), then find the value of sin2A.
If √3 tan x = 3, then the value of x:
If sin5A = cos(2A+20°), then what is the value of A? Given that 5A is an acute angle.
