Question : A train crosses a stationary pole completely in 18 seconds and a bridge completely in 44 seconds. If the length of the bridge is 650 meters, then what is the length of the train?
Option 1: 540 m
Option 2: 360 m
Option 3: 450 m
Option 4: 270 m
Correct Answer: 450 m
Solution : Let the length of the train be $l$ and the speed of the train be $s$. Time = 18 sec So, $s = \frac{l}{18}$ --------(i) Length of the bridge = 650 m Total distance = $650+l$ Time = 44 sec $s = \frac{650+l}{44}$ --------(ii)
Question : Directions: In the following question, find the odd number from the given alternatives.
Option 1: 95
Option 2: 145
Option 3: 114
Option 4: 152
Correct Answer: 145
Solution : Let's check the given options –
First option: 95; 95 ÷ 19 = 5 Second option: 145; 145 is not divisible by 19. Third option: 114; 114 ÷ 19 = 6 Fourth option: 152; 152 ÷ 19 = 8
So, 145 is not divisible by

Question : A and B can do a piece of work in 36 days. B and C can do the same work in 60 days. A and C can do the same work in 45 days. In how many days can A alone complete the same work?
Option 1: 90
Option 2: 60
Option 3: 120
Option 4: 45
Correct Answer: 90
Solution : According to the question, Let the total Work = LCM of 36, 60 and 45 = 180 The efficiency of (A + B) = $\frac{180}{36}$ = 5 units/day The efficiency of (B + C) = $\frac{180}{60}$ = 3 units/day The efficiency of (C + A)
Question : $\triangle$XYZ is right angled at Y. If $\cos X=\frac{3}{5}$, then what is the value of $\operatorname{cosec}Z$?
Option 1: $\frac{3}{4}$
Option 2: $\frac{5}{3}$
Option 3: $\frac{4}{5}$
Option 4: $\frac{4}{3}$
Correct Answer: $\frac{5}{3}$
Solution : Given: $\triangle$XYZ is right-angled at Y and $\cos X=\frac{3}{5}$ Since $\triangle$XYZ is right-angled at Y, So, X + Z = 90° ⇒ X = 90° – Z Now, $\cos X=\frac{3}{5}$ ⇒ $\cos(90°–Z)=\frac{3}{5}$ ⇒ $\sin Z=\frac{3}{5}$ $\therefore\operatorname{cosec}Z=\frac{5}{3}$ [$\because$ $\operatorname{cosec}Z=\frac{1}{\sin Z}$] Hence, the correct answer is $\frac{5}{3}$.
