1
Saurav travels from Delhi to Patna. He stops at equidistant places, that is Kanpur, Allahabad and Gaya during his journey. He covers the first one-fourth distance at a speed of 60 km/hr, the second one-fourth distance at a speed of 30 km/hr, third one fourth distance at a speed of 40 km/hr the last one-fourth distance at a speed of 60 km/hr. However, while returning, his uniform speed is 60 km/hr and he stops only at Jaunpur, which is exactly at the mid-point between Delhi and Patna. What is the average speed (in km/hr) of Saurav during the whole journey, not considering his halt time?
» Explain it
A
Suppose total distance between Delhi to Patna is x

Average speed =  total distance travelled
total time taken

Total distance travelled during whole journey = 2x

  x   x   x   x        
Total time taken =  4  +  4  +  4  +  4  +  x  =  19x
60 30 40 60 60 480

Required average speed =  2x  = 50.52 km/hr
19x
  480  

Hence, option A is correct.
2
In 2016 the ratio of salaries of Muskan and Babli was 2 : 3. The ratios of the salary of 2016 to that of the 2017, in the case of Muskan and Babli respectively, are 3 : 4 and 5 : 7. If this year i.e. 2017 the difference in their salaries is 2300, what is Babli’s salary this year?
» Explain it
B
Let a year ago i.e. in 2016 Muskan and Babli’s salaries were x and y and now it is m and n respectively.

Given that,

x  =  2           ......(i)
y 3

x  =  3          ......(ii)
m 4

y  =  5           ......(iii)
n 7

From (i) and (ii),

m  =  (2 × 4)  =  8           ......(iv)
y (3 × 3) 9

From (iii) and (iv)

m  =  (8 × 5)  =  40
y (9 × 7) 63

n  =  63
m 40

n  – 1 =  63  – 1
m 40

n – m  =  63 – 40
m 40

n – m  =  23            .....(v)
m 40

Also, given that (n – m) = 2300

Putting the value In equation (v)

2300  =  23
m 40

m =  40 × 2300  = 4000
23

So, n = 4000 + 2300 = 6300

Hence, option B is correct.
3
A man rows to a certain place(downstream) and comes back(upstream), but by mistake he covers 1/3rd more distance while coming back. The total time for this journey is 10 hours. The ratio of speed of boat to that of stream is 2: 1. If the difference between upstream and downstream speed is 12km/hr, then how much time will the man take to reach to starting point from his present position?
» Explain it
D
Speed of boat and stream be 2x and x respectively.

So downstream speed = 2x + x = 3x,

Upstream speed = 2x – x = x

Let total distance between points is d km

So he covered d km downstream,

While coming back i.e. upstream he covers d +  1  × d =  4d km
3 3

Total time for this journey is 10 hrs.
⇒  d  +  4d  = 10
3x 3x

⇒ d = 6x

Now also given, that (2x + x) – (2x – x) = 12

⇒ x = 6

So, d = 36 km
Now to come to original point, he will have to cover 1  × 36 = 12 km
3

And with speed 3x = 18 km/hr (downstream)
Hence, time is  12  × 60 = 40 minutes
18

Therefore, option (D) is correct.
4
Water flows out at the rate of 20 m/min from a cylindrical pipe of radius 5 mm. Find the time taken to fill a conical tank whose diameter at the surface is 40 cm and depth 24 cm.
» Explain it
B
Volume of cone =  1 πr2h
3

1  ×  22  × 20 × 20 × 24
3 7

= 10057.14 cm3

Radius of pipe = 5 mm

= 0.5 cm

Volume of water flowing out of the pipe per minute (in cm3)

= 1000 × 0.5 × 0.5 × π

= 785 cm3

Hence, time taken to fill the tank

10057.14
785

= 12.8 minutes

Hence, option B is correct.
5
It takes 30 minutes to empty a half-full tank by draining it at a constant rate. It is decided to simultaneously pump water into the half-full tank while draining it. What is the rate at which water has to be pumped in so that it gets fully filled in 10 minutes?
» Explain it
A
Drainage pipe can drain complete tank in 60min.

Let the filling pipe can fill the tank in x min

Now, both are operational and tank is half filled

Also remaining half needs to get filled in 10 min

10  { 1  –  1 }  =  1
x 60 2

⇒ x = 15min.
Hence, filling pump needs to have rate be  60  
15
= 4 times the draining rate.

Therefore, option (A) is correct.
