Test: General Aptitude - 1 - Physics MCQ

Each time we take 1 litre from 8 litre, 7 litre is left. So, the original: remaining of syrup is
8:7
So, each tune we take out there would be 7/8th part left of the syrup.
8 lit (as two tunes done)
=49/8 litre syrup left
Therefore, water = total - remaining

Therefore, syrup left: water 

Exceed is not followed by “more than'"

Let he has played x matches
Therefore, average 750/x runs/match.
After scoring 6 mroe runs, his total is (750 + 6) = 756 runs To score 6 more runs he has played 2 more matches Therefore, total matches played = (x + 2)
Therefore, now average runs/match = 756/x+2
As per condition,

Let total work = x
Therefore, one daywork of Ram = x/28
Therefore, one day work of Shyam= x/35
In 17 days work of Shyam = 
Remaining work = 
Now, in 1 day Ram and Shyam does

∴ 9x/140 = work done in 1 day
1 work done in 140 / 9x days
18x / 35 work done in = 8 days
Therefore, after working 8 days Rani left

Total distance to be covered to cross each other is the total length of both the trains. If length of both the trains are x. Then total distance to be covered = 2x First train in 8 secs goes x
First train in 1 secs goes x/8
Second train in 6 secs goes x
Second train in 1 secs goes x/6
Therefore, in 1 sec goes  (as in opposite direction)

Now, 14x / 48  goes m 1 sec
Therefore, 2x goes in 

Down stream speed = 30/10 = 3km/hr = U+V
Up stream speed = 18/10 = 1.8 km/hr = U-V
Velocity of water = 

 ∴ 

Falling from 600 and again going up by  


Each next term is being multiplied by 2/3 
a= 1000, r = 2/3 i.e. G.P. series
Therefore, sum =

Let us assume that we are standing at a point E somewhere on the road from where we are spectating.
Now, two poles are AB and CD; equal height i.e. AB = CD
From, 
And similarly from ΔCDE,  
∴ 
∴  

Area in between = area of the triangles - are covered by circles

(As each side of the equilateral triangle is 20 m and as angle of total 180° is covered by circles, i.e. half of 360°)

Volume of cone = volume of cuboid

Total triangles, in the upper part = 28
And in lower part is 3
therefore, total triangle is 28 + 3 = 31

Assuming the team consists of 11 players in total, with one of them being the captain, we need to select 10 players from the 14 available players.

So, only intersection between crows and Rats;
Therefore, only 2 Follows.

1³ + 2³ = 9
3³ + 4³ = 91
5³ + 6³ = 341 

In each quadrant area is  square unit
Therefore, in all four quadrants area is 32 x 4 = 128 square unit
