Question : Two tourist buses start from the same point and move along two roads at right angles at speeds of 48 km/hr and 36 km/hr, respectively. The distance between the buses after 15 seconds is ________.
Option 1: 175 m
Option 2: 350 m
Option 3: 250 m
Option 4: 150 m
Correct Answer: 250 m
Solution : Speed of Bus A = 48 km/hr = $48×\frac{5}{18}=\frac{40}{3}$ m/s Speed of bus B = 36 km/h = $36×\frac{5}{18}=10$ m/s Distance covered by bus A in 15 sec ⇒ Distance = $\frac{40}{3}$ × 15 = 200 m Distance covered by bus B in 15
Question : The radius of a large solid sphere is 14 cm. It is melted to form 8 equal small solid spheres. What is the sum of the total surface areas of all 8 small solid spheres? (use $\pi=\frac{22}{7}$)
Option 1: 3648 cm2
Option 2: 4928 cm2
Option 3: 4244 cm2
Option 4: 4158 cm2
Correct Answer: 4928 cm2
Solution : Given: The radius of a large solid sphere is 14 cm. The volume of the sphere of radius $r$ is $\frac{4}{3}\times \frac{22}{7}\times r^3$. Its total surface area is $4\times \frac{22}{7}\times r^2$. The volume of a large solid sphere is $\frac{4}{3}\times \frac{22}{7}\times (14)^3=11499$ cm
