The Sawa Lake, a biodiverse wetland situated near the city of Samawa, Iraq has disappeared mainly due to human activity and climate change.

• Since pipe B is faster than pipe A and thus, the tank will be emptied.

• Part of the tank to be emptied = 2/5

• Part emptied by (A+B) in 1 minute= (1/6 - 1/10) = 1/15.

Therefore,

⇒ 1/15 : 2/5 :: 1: x

⇒ 2/5 * 15 = 6 minutes

From the given data, we can get

• A's one day work = 1/24,

• B's one day work = 1/9 and

• Cs one day work = 1/12.

Since, B and C start the work and left after 3 days;

• the work done by B and C is = 3 *((1/9) +(1/12)) = 7/12.

• Therefore, remaining work = 1- 7/12 =5/12.

• Time taken by A to complete the remaining work = 24 * 5/12 =10 days.

• Let, the time is taken by pipe A = x

• Then, time is taken by pipe B = x/3

• By substituting these values, we get: 1/x + 3/x = 1/32 x = 128 minutes

• Work done by A in one day = 1/6.

• Work done by B in one day = 1/8

• Work done by C in one day = 1/3 - (1/6+1/8) = 1/3 -7/24 = (8-7)/24 = 1/24.

A's wage : B's wage : C's wage = 1/6 : 1/8 : 1/24 = 4: 3: 1

Therefore, C's share = (1/8) * 3200 = Rs 400.

9×360 children = 18×72 men = 12×162 women

⇒ 45 children = 18 men

= 27 women

⇒ 5 children = 2 men = 3 women

Now, 4 men + 12 women + 10 children

= 4 men + 8 men + 4 men

= 16 men

∵ 18 men can complete the work in 72 days.

∴ 16 men can complete the work in =18×72/16 = 81 days

Let B's 1 day work =x.

Then , A's 1 day's work=2x

X+2x=1/12

⇒ 3x=1/12

⇒ x=1/36.

B's 1 day work=1/36.

Hence B alone can finish the work in 36 days.

Given condition:

Speed of the boat in still water = 6 km/hr.

Speed of boat in downstream = 3 * speed of boat in upstream.

Let the speed of the current be 'x' km/hr.

Therefore, speed of the boat in upstream (i.e against the current) = (6-x) km/hr.

Speed of the boat in downstream (i.e in the direction of current) = (6+x) km/hr

Now, substituting values in given condition, we get

⇒ (6+x) = 3 * (6-x)

⇒ 6+x = 18-3x

⇒ 4x=12

⇒ x=3 km/hr 

Thus, speed of the current = 3 km/hr.

Let the distance between Tina's house and school be 'x' km.

Therefore, time to cover the distance from her house to school = (Distance/ speed) = (x/3) hours.

Similarly, time to cover the distance from her school to house = (x/2) hours.

It is given that total time taken for whole journey= 5 hours.

Thus, (x/3 + x/2)= 5

⇒ ((2x+3x)/6)= 5

⇒ (5x/6) = 5

⇒ 5x=30 or x=6

Thus, distance between her house and school is 6 km

It is given that: Speed in still water = 8 km/hr

Speed of the stream = 4 km/hr

Speed of upstream = (8-4) = 4 km/hr

Speed of downstream = (8+4) = 12 km/hr

Total time = 1.5 hrs

Let x is the distance.

Then substituting the values, we get

x/12 + x/4 = 3/2

x = 4.5 km

Average speed = 2xy/(x + y) km/hr

= (2 x 70 x 55)/ (70 + 55) km/hr

= (2 x 70 x 55)/125 km/hr

= 308/5 km/hr

= 61.6 km/hr

Let the speed of two trains be 7x Kmph and 8x kmph (speed of second train)

Then, 8x = 400 kms/4hrs = 100kmph

Therefore, speed of first train = 7x = (8/7) * 100

Speed of first train = 87.5 kmph

• Ratio of speeds = (550 m/60s * 18/5) : (60 * 33/45) = 33: 44 = 3: 4

Speed = 9km/hr = ( 9 * 5/18)m/sec = 5/2 m/sec

Total Distance = Perimeter of Square

4 * side of the square = 35 *4 = 140 m

Therefore, time taken = Distance /Speed = 140/(5/2) = 140* 2/5 = 28 *2 = 56sec

Standard Formula: If two objects A and B begin their journey at the same time from two points P and Q towards each other and after crossing each other they take a and b hours in reaching Q and P respectively, then

A's Speed Vb

B's Speed Va

By looking at the above problem, we can say that, a=9 hours, b=16 hours.

Therefore, Ratio of speeds of two trains = V16/V9 = 4/3 or 4:3

Standard Formula: Suppose A and B are two objects with lengths L1 and L2 respectively, and their speeds are S1 and S2 respectively and moving in opposite direction, then

• Crossing Time(Ct) = Length of the objects/ Relative speed of the object(s)

Thus, Ct= (L1+L2)/(S1 +S2)

By looking at the above problem, we can say that,

• L1 = 150 m,

• L2 = 180 m,

• S1 = 50 km/hr

• S2 = 58 km/hr

Relative speed= (S1+S2)= 108 km/hr or (108 * 5/18) m/s = 30 m/s.

Therefore, crossing time Ct= (L1+L2)/ Relative speed

Ct= (150 m+180 m)/ 30 m/s

Ct= 330 m / 30 m/s = 11 seconds

Let the number of lions = x

We know that the number of tigers in a zoo is three times the number of lions. Hence, the number of tigers = 3x.

Then, x + 3x = 4x = total number of animals.

Thus the total number of animals is a number that must be divisible by 4.

Here, 42 is the only number which is not divisible by 4.

Let the present ages of Sameer and Anand be 5x years and 4x years respectively.

Then (5x +3)/(4x+3)= 11/9

By solving the equation, we get x=6.

Therefore, Anand's present age= 4x= 24.

Number of liters of water in150 liters of the mixture = 20% of 150 = 20/100 * 150 = 30 liters. P liters of water added to the mixture to make water 25% of the new mixture.

Total amount of water becomes (30 + P) and total volume of mixture is (150 + P).

(30 + P) = 25/100 * (150 + P)

120 + 4P = 150 + P

⇒ P = 10 liters.

Original ratio of A, B, and C = 1/2 : 1/3 : 1/4 = 6: 4: 3 Share of A = 6/13 * 117 = Rs. 54 Share of B = 4/13 * 117 = Rs. 36 Share of C = 3/13 * 117 = Rs. 27

The ratio of A, B, and C by mistake = 2 : 3 : 4 Share of A = 2/9 *117 = Rs.26 Share of B = 3/9 *117 = Rs.39 Share of C = 13 * 4 = Rs.52

Therefore, it is clear from the above calculation that C gains maximum i.e. 52 - 27 = Rs. 25

Let the original salary of Santhosh and Revathi be 6x and 5x respectively Then, (6x+6000) / (5x+6000) = 38/35 35(6x+6000) = 38(5x +6000)

210x +210000 = 190x + 228000 210x - 190x = 228000 - 210000 20x= 18000 X = 900

Revathi's present salary = 5x = 5*900 = Rs. 4500

Let the cost price of one shirt be x and cost price of one jean be y.

2x + 3y = 2200 ...(i)

2y + 4x = 2400 or 2x + y = 1200 ...(ii)

By solving the equation (i) and (ii),

x = Rs.350; y = Rs. 500

Therefore the required ratio = 500 : 350 = 10 : 7

Given, ratio of two numbers = 7: 9 Let two numbers be 7x and 9x

If 12 is subtracted from each number, then new numbers are (7x -12) and (9x - 12)

It is given that (7x-12)/(9x-12) = 3/5

⇒ 5(7x - 12) = 3(9x - 12)

⇒ 35x - 60 = 27x - 36

⇒ 8x = 24 or x = 3

Product of the numbers = 7x * 9x = 7(3) * 9(3)

= 21 * 27 = 567

• Let the length and breadth of the rectangle be x and y units respectively

• Original area= xy units²

• New area= (0.9x) x (0.9y) =0.81xy units²

• Percentage decrease in area= (0 .81xy- xy/xy) x 100= -19% (Negative sign indicates decrease in area)

Selling Price (S.P.) = Rs100 - Rs12.5 = Rs. 87.5

S.P. after 6% gain = Rs106 Difference = Rs.18.5

Therefore, Cost Price (C.P.) = (92.5/18.5) x 100 = Rs.500

Milk contains 25% water and 75% milk.

Therefore, 1 liter milk contains only 750 ml of milk.

Cost of 750 ml milk = 40 * (750/1000) = 40 * 3/4 = Rs. 30

Since, 750 ml of milk is diluted to one liter and sold at the rate of Rs. 50 per liter.

Selling price of 1 Liter milk = Rs. 50.

Profit per liter = Rs. 50 - Rs. 30 = Rs. 20.

Let the marked price of the article be Rs. x Discount = 10%

Then, the selling price = - 10% of = (9x/10)

Now,= (9x/10)= 6750 Or x = Rs. 7,500

As per the question, if the selling price is Rs. 7,500,

then the profit earned by the Ramesh is 50%.

So, the cost price = Rs. 5,000

Therefore, the actual percentage of profit earned by selling the article for Rs. 6,750 = (Profit/CP) x 100 =(1750/5000)x 100 = 35%

Since, Ramya invested for 8 months and Sheela invested for 10 months, Ratio of their shares = (35000 * 8 ) : (42000 * 10) = 2 : 3.

Ramya's share Rs. 31570 * (2 / 5) = Rs. 12628.

Let the original number be x.

If number is decreased by 10% and then increased by 10%, then Final number obtained = 110% of (90% of x)

= (110/100 * 90/100 * x)

= (99/100)x.

By the given data, number so obtained is 10 less than the original number,

Therefore x- (99/100)x=10 or x =1000

Let the cost price = x

Therefore selling price with 60% profit = 160/100 x =8/5 x

It is given that selling price is 38 more than one-third of cost price

(8/5) * x = x/3 + 38 (8/5 - 1/3) * x = 38 ((24 - 5)/15) * x = 38 x = 38 * 15/19 x = 30

Therefore, cost price = Rs 30
