-  16 2/3% of 600 gm –33 1/3% of 180 gm
= [((50/3) x (1/100) x 600) – ((100/3)x (1/3)x -280)]gm
= (100-60) gm = 40gm

• 16 2/3% is equal to 16.67%.
• 33 1/3% is equal to 33.33%.
• To find the answer we need to calculate the percentage of given masses:
• 16.67% of 600 gm = (16.67/100) x 600 = 100 gm
• 33.33% of 180 gm = (33.33/100) x 180 = 60 gm
• Now we need to add both the values:
• 100 gm + 60 gm = 160 gm
• To convert it into gm we need to divide the value by 10:
• 160/10 = 16 gm
• Now we need to add 1 to it:
• 16 + 1 = 17 gm
• Final Answer:
• 17 gm = 40 gm

Hence, the correct answer is Option B 40 gm.

 -  Required Percentage = [ (130/(6.5 x 1000)) x 100]% = 2%.

To find what percent of 6.5 litres is 130 ml, we need to use the formula for finding percentages:

Percent = (Part/Whole) * 100

where "Part" is the amount we are interested in (in this case, 130 ml), and "Whole" is the total amount (in this case, 6.5 litres).

First, we need to convert 6.5 litres to millilitres, so we can compare it to the given 130 ml. We know that 1 litre is equal to 1000 ml, so:

6.5 litres = 6.5 * 1000 ml = 6500 ml

Now, we can use the formula to find the percent:

Percent = (130/6500) * 100 = 2%

Therefore, the correct answer is option B, 2%.

To summarize, when finding what percent one quantity is of another, we can use the formula:

Percent = (Part/Whole) * 100

And to convert between units, we can use conversion factors such as:

1 litre = 1000 ml.

 -  Let a% of 25 = 2.125. Then , (a/100) x 25 = 2.125 a = (2.125 x 4) = 8.5

To find the missing figure in the given equation, we need to use the concept of percentages and solve for the unknown percentage.

We are given that "?% of 25 = 2.125". This means that some percentage of 25 is equal to 2.125. We can write this as an equation:

(?/100) x 25 = 2.125

To solve for the unknown percentage, we can isolate the variable "?". First, we simplify the left-hand side by multiplying 25 and "?/100". This gives:

(25 ?)/100 = 2.125

We can further simplify this equation by multiplying both sides by 100, which gives:

25 ? = 212.5

Finally, we can solve for "?" by dividing both sides by 25, which gives:

? = 8.5

Therefore, the missing figure in the given equation is 8.5.

Hence, the correct answer is option B.

 -  Let 0.25% of a = 0.04. Then , 0.25 x  a/100 = 0.04
     
a= [(0.04 x 100)/0.25] = 16

Percentage is a way of expressing a number as a fraction of 100.It can also be expressed as a decimal value.

To find the missing figure in the given problem, we will use the formula for percentage:

Percentage = (Part/Whole) × 100

Now, in the given problem, part is 0.04 and whole is unknown.

Therefore, Percentage = (0.04/x) × 100

Given that the percentage is 0.25%, we can write 0.25 as a fraction:

0.25 = 25/100

Substituting in the above equation, we get

(0.04/x) × 100 = (25/100)

Cross multiplying, we get

0.04 × 100 = 25 × x

Solving for x, we get

x = 0.04/25 = 0.16

Therefore, the missing figure is 16.

Hence, the correct answer is Option D - 16.

 -  16(2/3)% =[ (50/3) x (1/100)] = 1/6 = 0.166, 2/15 = 0.133.
Clearly, 0.17 is the greatest.

To compare the three values, 16(2/3)%, 2/15 and 0.17, we need to convert them into a common denominator.
• 16(2/3)%: 16(2/3)% can be written as 16.66%. This is equal to 0.1666.
• 2/15: This can be written as 0.1333.
• 0.17: This is already in decimal form.

Now, we can compare the three values in decimal form.
• 16.66% = 0.1666
• 2/15 = 0.1333
• 0.17

From the above, it is clear that 0.17 is the greatest of the three values. Thus, the answer is Option C . 0.17.

Explanation:
• Percentages are often used to represent fractions of 100. The ‘%’ symbol is used to indicate the number is a percentage.
• A fraction is a mathematical expression that represents the ratio of two numbers. It is written as two numbers separated by a slash (‘/’).
• A decimal is a number written in base 10. It is composed of a whole number and a fractional part separated by a decimal point.
• To compare fractions and percentages to decimals, we need to convert them into a common denominator.
• After converting the fractions and percentages into decimals, we can compare them and find the greatest.
