Question three. How Much Space Would A 30 Cup Shelf Require If A 12 Shell Cupboard Requires 18 Ft. Of Wall Space?

Answer :

A 30 Cup shell requires forty five feet. Of wall.

Question 4. In A Staff Room, There Are Four Racks With 10 Boxes Of Chalk-stick. In A Given Day, 10 Boxes Of Chalk Stick Is In Use. What Is The Fraction Remains In The Rack?

Answer :

If every rack consist of 10 container of chalk stick, then overall number of field on four racks might be

4X 10 = forty

Now, the second one component is 10 of the boxes are in use which means that that overall quantity of field left is= 40 – 10 = 30.

Now the fraction may be

Remained/ general = 30/ forty = 3 / 4 is the fraction continue to be in the rack.

Question five. Explain What Is The Formula For Calculating Interest Rate?

Answer :

There are two styles of interest which can be calculated using a one-of-a-kind formula

Simple Interest

Compound Interest

To calculate simple interest, formulation used is (PX RX T)/ one hundred

Where P is the important quantity, R is for the rate of interest and t is for time

Formula for calculating compound hobby is P X (1 + r/100) ^t

Question 6. Explain What Is Commutative, Associative And Distributive Laws In Maths?

Answer :

Commutative laws say we will change numbers, and you still get the equal range whilst you upload, for example, a+b = b+a and equal for multiplication.

Associative laws say it does no longer depend how we organization the range final cost will continue to be the identical, for example, (a+b)+c = (a+b)+c , and equal for multiplication

Distributive legal guidelines say that we can have the same solution while multiplying a number of via a set of numbers brought together or multiplying them separately after which upload them, For instance, a x ( b+c) = axb + bxc.

Question 7. In A Small Company Average Salary Of Three Employees Is $1000 Per Week. If One Employee Earns $1100 And Other Earns $500, How Much Will The Third Employee Earn?

Answer :

Formula to calculate this:

(e1+e2+e3) /3 = $ one thousand

1100+500+e3 = a thousand x three

1600+e3 = 3000

e3 = 3000-1600

= 1400

The third employee will earn $1400.

Question 12. Explain How You Can Convert A Fraction To A Percentage?

Answer :

To convert a fraction to a percent, we investigate an instance for 4/nine

First divide 4/9 = 0.Forty four
Then multiply through one hundred = zero.Forty four x one hundred = forty four.Forty four
Add the “ % “ signal to the answer = 44.Forty four%
Percentage of 4/9 = forty four.Four %
Math Fundamentals Interview Questions
Question thirteen. Explain How You Can Convert A Percentage To A Fraction?

Answer :

To convert a percent into fraction permit say 70% to a fragment

Convert 70 % into decimal = 70/ one hundred = zero.7
Write down the decimal “over” the number 1 = zero.7/1
Then multiply pinnacle and bottom with the aid of 10 = 0.7x 10 = 7/10
For every variety after the decimal point 1 x 10

(10 for 1, a hundred for two)

Which will deliver = 7/10
7/10 it the fraction shape
Question 14. Explain What Is Cubic Meter?

Answer :

Cubic Meter is the usual unit used to measure the volume of an object length via period. The unit is written in m3.

1 m3 (Cubic Meter) = 1000 liters

Question 15. Explain How Much Is A Hectare And How Much Is Square Millimetre?

Answer :

1 hectare = 100 meters on every facet , so a hectare has a hundred m x 100 m = 10,000 m2

A square millimetre is millimetres x millilitres; a millimetre is one thousand part of a meter, so a square millimetre is one millionth of a rectangular meter

1 X 1 = 1 of a rectangular meter

a thousand a thousand 1,000, 000
