A এর সময় লাগে 2x দিন

এবং, C এর সময় লাগে y দিন

A এর সময় লাগে 3y দিন

এখন, 2x = 3y

y = 2x/3

A : B : C = 2x : x : 2x/3 = 6x : 3x : 2x

Answer: Option D

Explanation:

To find the percent of sodium chloride in the remaining solution, we'll calculate the initial amount of sodium chloride and then find the percentage after 2500 gallons of water evaporate.

Initial amount of sodium chloride = 5% of 10,000 gallons Initial amount of sodium chloride = (5/100) * 10,000 = 500 gallons

Initially, there are 500 gallons of sodium chloride in the solution.

After 2500 gallons of water evaporate, there are 10,000 - 2500 = 7500 gallons of liquid remaining in the tank.

Now, to find the percentage of sodium chloride in the remaining solution:

Percentage of sodium chloride = (Amount of sodium chloride / Total volume of solution) * 100

Percentage of sodium chloride = (500 gallons / 7500 gallons) * 100

Percentage of sodium chloride ≈ 6.67%

So, the remaining solution will be approximately 6.67% sodium chloride.

1178 . A tank is 30% full with water. If 18 liters of water is added the tank become 3/4 full. What is the capacity of the tank?

A. 36
B. 40
C. 45
D. 56

View Answer	Favorite Question

Answer: Option B

Explanation:

3/4 ≡ 3/4 x 100% = 75%

Change in = 75% - 30% = 45%

Now, 45% capacity = 18 liter

So, 100% capacity = 18 x 100 / 45 = 40 liter

1179 . A tank is 40% full of water. If 9 liters of water is removed, the tank becomes 1/4th full. What is the capacity of the tank in liter?

A. 20
B. 30
C. 40
D. 60

View Answer	Favorite Question

Answer: Option D

Explanation:

Let's call the capacity of the tank "C" liters. Initially, the tank is 40% full of water, which means it contains 0.4C liters of water. When 9 liters of water are removed, it becomes 1/4 full, which means it contains (1/4)C liters of water.

We can set up an equation using this information:

0.4C - 9 = (1/4)C

Now, let's solve for C:

0.4C - 9 = (1/4)C

Multiply both sides of the equation by 4 to eliminate fractions:

1.6C - 36 = C

Subtract C from both sides:

0.6C - 36 = 0

Now, add 36 to both sides:

0.6C = 36

Finally, divide by 0.6 to find the capacity of the tank:

C = 36 / 0.6 = 60

So, the capacity of the tank is 60 liters.

1180 . A tank is filled in 5 hours by three pipes A,B and C The pipe C is twice as fast as B and B is twice as fast as A How much time will pipe A alone take to fill the tank?

A. 20 hours
B. 25 hours
C. 35 hours
D. None of these

View Answer	Favorite Question

Answer: Option C

Explanation:

Suppose pipe A alone takes x hours to fill the tank.
Then, pipes B and C will take x/2 and x/4 hours respectively to fill the tank.
∴1/x + 2/x + 4/x = 1/5
⇒7/x = 1/5
⇒x = 35hours

A. 88
B. 98
C. 60
D. 122

View Answer	Favorite Question

Answer: Option C

Explanation:

Hints: ধরি, . math mark = m, social studies = s

1/3 m = 1/2s + 30

এবং, m + s = 240

m = 240 - s

তাহলে, 1/3(240 - s) = 1/2 s + 30

80 - s/3 = 1/2 s + 30

1/2s + s/3 = 80 - 30

3S + 2S / 6 = 50

5s = 300

S = 60

1185 . A time-study specialist has set the production rate for each worker on a certain job at 22 units every 3 hours. At this rate what is the minimum number of workers that should be put on the job if at least 90 units are to be produced per hour?

A. 12
B. 13
C. 18
D. 30

View Answer	Favorite Question

Answer: Option B

Explanation:

The rate for each worker can be expressed as 22/3 units per hour.

We can let n = the number of workers needed to produce 90 units per hour, and we have:

n(22/3) = 90

or,22n = 270

∴ n = 270/22 = 12.2,

so there must be at least 13 workers.(ans)
