Question : A boat covers a distance of 12 km in 1 hour upstream and in 45 minutes downstream. Find the speeds of the boat and the stream (in km/hr).
Option 1: 16 and 4
Option 2: 16 and 2
Option 3: 14 and 2
Option 4: 12 and 4
Correct Answer: 14 and 2
Solution : Let the speed of the boat be x km/hr and the speed of the stream be y km/hr. So, downstream speed = x + y = $\frac{12×60}{45}=16$ km/hr............(1) Upstream speed= x – y = 12 km/hr...........(2) By solving the above equations, we get,

Question : $\triangle DEF$ is right angled at E. EC is the altitude. CF is 18 cm and FD is 26 cm. What is the length of FE?
Option 1: $2\sqrt{13}$ cm
Option 2: $6\sqrt{13}$ cm
Option 3: $12$ cm
Option 4: $15$ cm
Correct Answer: $6\sqrt{13}$ cm
Solution : FD = 26 cm CF = 18 cm ⇒ CD = 26 – 18 = 8 cm EC2 = CD × CF = 8 × 18 = 144 ⇒ EC = $\sqrt {144}$ = 12 cm In $\triangle$ECF, $\angle$ C = $90^{\circ}$ By
Question : The pie chart given below shows the number of boys in 8 schools. The total number of boys in all these 8 schools is 10000. The number of boys in a particular school is shown as a percent of the total number of boys in all these 8 schools. What is the ratio of the central angle formed by sectors C, D, and F together to the central angle formed by sectors A, G, and H together?
Option 1: 19 : 44
Option 2: 17 : 39
Option 3: 20 : 43
Option 4: 44 : 21
Correct Answer: 20 : 43
Solution : Use the formula, $\text{Required angle}=\frac{\text{Percent of sector}}{100}\times 360º$ The angle of the sectors, C = $\frac{12}{100}\times 360º$ = 43.2º D = $\frac{2}{100}\times 360º$ = 7.2º F = $\frac{6}{100}\times 360º$ = 21.6º The central angle formed by sectors C, D, and F together =
