Question
In the question below some statements are given
followed by two conclusions I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusion definitely follows from the given statements, disregarding commonly known facts. Statements: All Minerals are Vitamins Some Vitamins are Deficient No Iron are Deficient Conclusions: I. Some Iron are Minerals II. Some Vitamins are not IronSolution
All Minerals are Vitamins (A) + Some Vitamins are Deficient (I) → No conclusion. Hence conclusion I does not follow. Some Vitamins are Deficient (I) + [No Iron are Deficient (E) → Conversion] → No Deficient are Iron (E) → Some Vitamins are not Iron (O). Hence conclusion II follows.
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:
