500 soldiers in a fort had enough food for 30 days but 125 soldiers were transferred to another fort. For how many days did the food last then?
Find the value of \(7875 \times 4574 \times697 \over82\)
If θ is an acute angle and tan θ + cot θ = 2, then the value of \(tan^{200} θ + cot^{200} θ\) is:
If x & y are acute angle, x+y <90° & sin(2x - 20°) = cos(2y + 20°), the value of sec(x + y) is
