**Answers & Solutions:**

**1)Â AnswerÂ (B)**

To complete one round Ram takes 100m/15kmph and Rahim takes 20m/5kmph

They meet for the first time after L.C.M of (100m/15kmph , 20m/5kmph) = 100m/5kmph=20m/kmph.

Distance traveled by Ram =20m/kmph * 15kmph =300m.

So, he must have ran 300/100=3 rounds.

**Note:**

CAT gave both 2 and 3 as correct answers because of the word ‘**before**‘.

**2)Â AnswerÂ (A)**

Let the distance from A to B be “x”, then the distance from B to C will be 3x. Now the speed of Train 2 is double of Train 1. Let the speed of Train 1 be “v”, then the speed of Train 2 will be “2v” while travelling from AÂ to B.

Time taken by Train 1 = (x/v)

Time taken by Train 2 = (x/2v)

Now from B to C distance is “3x” and the speed of Train 2 is (v) and the speed of Train 1 is (2v).

Time taken by Train 1 = 3x/2v

Time taken by Train 2 = 3x/v

Total time taken by Train 1 = x/v(1+(3/2)) = (5/2)(x/v)

Total time taken by Train 2 = x/v(3+(1/2))= (7/2)(x/v)

Ratio of time taken =Â $\frac{5}{\frac{2}{\frac{7}{2}}}=\frac{5}{7}$

**3)Â AnswerÂ (A)**

Assume the total distance between A and B as d andÂ time taken by Amal = t

Since Amal travelledÂ $\frac{1}{3}^{rd}$ of his total journey time in different speeds

d =Â $\ \frac{\ t}{3}\times\ 10+\ \frac{\ t}{3}\times\ 20+\frac{\ t}{3}\times\ 30\ \ =\ 20t$

$\text{Total time taken by Bimal} =Â \ \frac{d_1}{s_1}+\frac{d_2}{s_2}+\frac{d_3}{s_3}$

$=\ \frac{20t}{3}\times\ \frac{1}{10}+\frac{20t}{3}\times\ \frac{1}{20}+\frac{20t}{3}\times\ \frac{1}{30}\ \ =\frac{20t\left(6+3+2\right)}{3\ \times30}\ =\frac{11}{9}t$

Hence, the ratio ofÂ time taken by Bimal to time taken by Amal = $\frac{\frac{11t}{9}}{t}=\frac{11}{9}$

Therefore, BimalÂ will exceed Amal’s time byÂ $\ \ \ \frac{\ \ \frac{\ 11t}{9}-t}{t}\times\ 100 = 22.22%$

**4)Â AnswerÂ (B)**

Time taken to meet =Â $\ \frac{\ Dis\tan ce\ between\ them\ }{Relative\ speed}$

Relative Speed = 5 +4 = 9 miles per hour.

Time take to cover 81 miles =Â $\ \frac{\ 81\ }{9}$ = 9 hours.

Woman travelled in 9 hours = 9*4 = 36 miles.

**5)Â AnswerÂ (A)**

Let t be the start time

A starts at t, while B starts at (t-2)

Total distance covered = 200 km

As they are travelling in the opposite direction,

Relative distance covered i,e 200=((200/4)*t )+((400/7)*(t-2))

t=176min i.e 2hrs 56min from start (6 am)

Therefore they meet at 8.56 am.

A is the correct answer.

**6)Â Answer:Â 20**

We see that the man saves 20 minutes by changing his speed from 12 Km/hr to 15 Km/hr.

Let d be the distance

Hence,

$\frac{d}{12} – \frac{d}{15} = \frac{1}{3}$

$\frac{d}{60} = \frac{1}{3}$

d = 20 Km.

**7)Â AnswerÂ (C)**

Let the distance between Hyderabad and Bangalore be $x$. and return speed be $y$km/hr

Distance covered with speed of 60km/hr = $\frac{2x}{5}$. Time taken =Â $\frac{2x}{5\left(60\right)}=\frac{x}{150}$

Distance covered with speed of 80km/hr = $\frac{3x}{5}$. Time taken = $\frac{3x}{5\left(80\right)}=\frac{3x}{400}$

The time taken for return journey = $\frac{x}{y}$

Upon equating time, we get

$\frac{x}{150}+\frac{3x}{400}=\frac{x}{y}$

$\frac{8x}{1200}+\frac{9x}{1200}=\frac{x}{y}$

$\frac{17x}{1200}=\frac{x}{y}$ orÂ $y=\frac{1200}{7}=70.58\ \frac{km}{hr}$

**8)Â AnswerÂ (B)**

The difference in the time take to traverse the same distance $’d’$Â at two different speeds is 35 minutes. Equating this:Â $\frac{d}{8}-\frac{d}{15}\ =\ \frac{35}{60}$

On solving, we obtain $d = 10 kms$. Let $x kmph$ be the speed at which Amal needs to travel to reach the office in 50 minutes; then

$\frac{10}{x}=\frac{50}{60}\ or\ x\ =\ 12\ kmph$.Hence, Option B is the correct answer.

**9)Â AnswerÂ (B)**

The speed of the trains in m/s: $T_1$ = 30 m/s and $T_2$=20 m/s respectively.

An initial representation of the positions of the trains and the bike is shown below:

Time taken by the Train T1 to reach the junction = 1500/30 = 50 seconds

Time taken by the Train T1 to completely cross the junction = (1500+150)/30 = 55 seconds

Time taken by the Train T2 to reach the junction = 1000/20 = 50 seconds

Time takne by the Train T2 to completely cross the junction = (1000 + 200)/20 = 60 seconds.

Hence the bike should not cross the junction between 50 seconds and 60 seconds.

=> 50Â $\leq$Â Time taken by the bike to reach the junctionÂ $\leq$ 60

=> $ SÂ \geq 600/50Â $ orÂ $ SÂ \leq 600/ 60$

=> $ S \geq 12 $ or $ S \leq 10$

**10)Â Answer:Â 50**

Assume the speed of

boat with respect to

water = v

Then, 120/(v-10) –

120/(v+10) = 1

=> v^2-100 = 2400

=> v=50 km/hr
