If A lies between 45° and 540°, and sin A = 0.5, what is the value of A/3 in degrees?
Two objects are moving on a circular path of length 160 km at a speed of 30 kmph and 50 kmph in the opposite direction. At how many point will both the objects meet on a circular path if they are continuously moving?
A dishonest grocer sells rice at a profit of 10% and uses weights which are 20% less than the marked weight. The total gain earned by him will be
