Question
There are seven persons Anmol, Fuzail, Raju, Enamul,
Dinesh, Badal and Chaman each of different professions Lawyer, Judge, Police, Professor, Architect, Engineer and Doctor but not necessarily in same order, sitting in a row facing towards North direction as per the given information • There is no person is sitting to the left of Judge. • Dinesh is sitting exactly in the middle of row. • Raju is sitting third to the left of Chaman. • Lawyer is sitting between Police and Anmol. • Fuzail is a professor sitting to the one end of row. • Badal is an engineer and Raju is a Lawyer. • Dinesh is neither police nor lawyer. Which of the following statement is/are true based on the given arrangement? I. Anmol is sitting to the left end of the row. II. Enamul is sitting third to the left of Badal. III. Doctor is sitting to the right of Chaman.Solution
The correct answer is B
If 0 ≤ θ ≤ 90°, and sin(2 θ +50°) = cos (4 θ + 16°), then what is the value of θ (in degrees)?
sin10˚ x sin20˚ x sin40˚ =?
If (2sin A + cos A) = 3sin A, then find the value of cot A.
If tan 4θ = cot 14θ, then find the value of cos 9θ.
If sin A = 3/5 and cos B = 4/5, where A and B are acute angles, find the value of sin(A + B).
If √3cosec 2x = 2, then the value of x:
If tan θ + cot θ = 2 where 0 < θ < 90 ; find the value of tan30 θ + cot 29 θ.
- If sin (3A − 4B) = (1/2) and cos (A + B) = (√2/2), where 0° < A, B < 90°, then find the value of ‘A’.
If θ is an acute angle and sin θ + cosec θ = 2, then the value of sin2 θ + cosec2 θ is:
