Given:
Capacity of cylindrical tank = 32 litres
Tank is 4/5 full of water
Quarter of water is poured into a pail

To find: How much water is left in the cylindrical tank?

Solution:

Step 1: Find the amount of water in the cylindrical tank
The cylindrical tank is 4/5 full of water
Therefore, the amount of water in the cylindrical tank = 4/5 x 32 = 25.6 litres

Step 2: Find the amount of water poured into the pail
One quarter of the water in the cylindrical tank is poured into the pail
Therefore, the amount of water poured into the pail = 1/4 x 25.6 = 6.4 litres

Step 3: Find the amount of water left in the cylindrical tank
The amount of water left in the cylindrical tank = Total amount of water - Amount of water poured into the pail
= 25.6 - 6.4 = 19.2 litres

Therefore, the answer is option B) 19 1/5 litres.

Given information:
- Average mass of 3 boys = 64 kg
- Total mass of 2 boys = 119 kg

To find: Mass of the third boy

Solution:
Let's assume the mass of the third boy as x kg.

We know that the average mass of 3 boys is 64 kg, which means the total mass of all 3 boys would be:

Total mass of 3 boys = Average mass of 3 boys × Number of boys
Total mass of 3 boys = 64 × 3
Total mass of 3 boys = 192 kg

Now, we also know that the total mass of 2 boys is 119 kg. So, we can find the mass of the third boy by subtracting the total mass of 2 boys from the total mass of 3 boys:

Mass of the third boy = Total mass of 3 boys - Total mass of 2 boys
Mass of the third boy = 192 - 119
Mass of the third boy = 73 kg

Therefore, the mass of the third boy is 73 kg.

Answer: Option B) 73 kg

The correct unit for measuring the amount of liquid needed to fill a small teacup is milliliter (ml).

Explanation:
- Milliliter is a unit of volume that is commonly used to measure small amounts of liquid. It is a metric unit and is equal to one-thousandth of a liter.
- The teacup mentioned in the question is a small container, and therefore, it requires a unit of measurement that is suitable for measuring small volumes of liquid.
- Gram and kilogram (options a and b) are units of weight or mass, not volume. They are used to measure the amount of matter in an object, not the amount of liquid it can hold.
- Meter (option c) is a unit of length, not volume. It is used to measure distance or size, not the amount of liquid in a teacup.
- Therefore, the correct unit for measuring the amount of liquid needed to fill a small teacup is milliliter (ml), which is option d.

To summarize:
- The unit for measuring the amount of liquid needed to fill a small teacup is milliliter (ml).
- Milliliter is a unit of volume and is suitable for measuring small amounts of liquid.
- Gram, kilogram, and meter are not appropriate units for measuring liquid volume in a teacup.

Given:
1 kg of rice costs as much as 1.25 kg of wheat flour.

Leela paid Rs 12.60 for 2 kg of rice and 5 kg of wheat flour.

To find:
The cost of 5 kg of wheat flour.

Solution:
Let's assume the cost of 1 kg of rice is Rs x.
According to the given information, 1 kg of rice costs as much as 1.25 kg of wheat flour.
So, the cost of 1.25 kg of wheat flour is also Rs x.

Now, we have the following information:
Cost of 2 kg of rice = Rs 12.60
Cost of 5 kg of wheat flour = ?

To find the cost of wheat flour, we can use the concept of ratios.

Ratio of cost of rice to cost of wheat flour = 2:5

So, we can set up the following equation using the given information:
2/x = 5/(1.25x)

Cross-multiplying the equation, we get:
2 * 1.25x = 5 * x

Simplifying the equation, we get:
2.5x = 5x

Subtracting 2.5x from both sides of the equation, we get:
2.5x - 2.5x = 5x - 2.5x
0.5x = 0

Dividing both sides of the equation by 0.5, we get:
x = 0

This means that the cost of 1 kg of rice is zero, which is not possible.

Therefore, there must be an error in the given information or the question itself.

The correct answer cannot be determined with the given information.

Hence, the options provided (a) Rs 1.68, (b) Rs 2.10, (c) Rs 8.40, and (d) Rs 10.50 are not valid answers.

Six

Given information:
- Total number of animals in the pet shop = 45
- Number of puppies = 23
- Number of parrots = 6

To find:
- Number of kittens in the pet shop

Solution:
- We know that the total number of animals in the pet shop is 45.
- We also know that there are 23 puppies and 6 parrots.
- Therefore, the number of kittens can be found by subtracting the number of puppies and parrots from the total number of animals.

Number of kittens = Total number of animals - Number of puppies - Number of parrots
Number of kittens = 45 - 23 - 6
Number of kittens = 16

Therefore, there are 16 kittens in the pet shop. The correct option is B.

Answer: Option B.

Given information:
- Number of pupils in the class = 30
- Stickers brought by each boy = 5
- Stickers brought by each girl = 4
- Total stickers brought by boys = Total stickers brought by girls + 60

Let's assume that there are 'b' boys in the class and 'g' girls in the class.

Total number of stickers brought by boys = 5b
Total number of stickers brought by girls = 4g

According to the given information, we can form the following equations:

5b = 4g + 60 ----(1) (Total stickers brought by boys = Total stickers brought by girls + 60)
b + g = 30 ----(2) (Total number of pupils in the class)

Now, we need to solve these equations to find the value of 'b', which represents the number of boys in the class.

Solving equation (2) for 'g', we get:

g = 30 - b

Substituting this value of 'g' in equation (1), we get:

5b = 4(30 - b) + 60

5b = 120 - 4b + 60

9b = 180

b = 20

Therefore, there are 20 boys in the class, which is option (C).
