5.	Sameera earms Rs 18500 per month. She spend 60% of it and saves the rest. How much amount she saves every month.
Answer» ✬ Saved Money = Rs 7400 ✬ Step-by-step explanation: Given: Sameera earns Rs 18500 PER month. She spends 60% of it and saves remaining. To Find: How much AMOUNT she saves every month ? Solution: Let she saves Rs x every month. ➟ Money spent by her = 60 % of total. ➟ 60/100 × 18500 ➟ 60 × 185 ➟ 11100 So she SPEND Rs 11100 per month from her earning. ∴ Saved money = (Total – Spent) money ➮ Saved money = Rs (18500 – 11100) ➮ x = Rs 7400 Hence, she saves Rs 7400 per month.

Sameera earms Rs 18500 per month. She spend 60% of it and saves the rest. How much amount she saves every month.

Answer»

✬ Saved Money = Rs 7400 ✬

Step-by-step explanation:

Given:

Sameera earns Rs 18500 PER month.
She spends 60% of it and saves remaining.

To Find:

How much AMOUNT she saves every month ?

Solution: Let she saves Rs x every month.

➟ Money spent by her = 60 % of total.

➟ 60/100 × 18500

➟ 60 × 185

➟ 11100

So she SPEND Rs 11100 per month from her earning.

∴ Saved money = (Total – Spent) money

➮ Saved money = Rs (18500 – 11100)

➮ x = Rs 7400

Hence, she saves Rs 7400 per month.

2.The sum of three numbers is 64. The second number is 3 less than the first number, the third is 11 less than twice the first. What are the numbers?

Answer»

Step-by-step explanation:

LET the FIRST number be x

According to the question

second number=x-3

third number=2x-11

x+(x-3)+(2x-11)=64

4x-14=64

4x=64+14

4x=78

x=78/4

x=19.5

therefore the first number is 19.5

second number is 19.5-3=16.5

third number is (2*19.5)-11=28

so the THREE numbers are 19.5,16.5and 28.

15.	Explain the types of number system in mathematics.
Answer» Answer: There are numbers like 1, 2, 3, ... etc., ones like 0.33333... , or ones like 5/7. We introduce students to these gradually, and each new type COMES with its own uses, and its own challenges.The main types of numbers used in school mathematics are listed below: Natural Numbers (N), (also called POSITIVE integers, counting numbers, or natural numbers); They are the numbers {1, 2, 3, 4, 5, …} Whole Numbers (W). This is the set of natural numbers, plus zero, i.e., {0, 1, 2, 3, 4, 5, …}. Integers (Z). This is the set of all whole numbers plus all the negatives (or opposites) of the natural numbers, i.e., {… , ⁻2, ⁻1, 0, 1, 2, …} Rational numbers (Q). This is all the fractions where the top and bottom numbers are integers; e.g., 1/2, 3/4, 7/2, ⁻4/3, 4/1 [Note: The denominator cannot be 0, but the numerator can be]. REAL numbers (R), (also called measuring numbers or measurement numbers). This includes all numbers that can be written as a decimal. This includes fractions written in decimal FORM e.g., 0.5, 0.75 2.35, ⁻0.073, 0.3333, or 2.142857. It also includes all the irrational numbers such as π, √2 etc. Every real number corresponds to a point on the number line. Students generally start with the counting numbers (N). They are then introduced to 0, and this gives them the whole numbers (W). The integers are avoided initially, even though simple subtraction could lead to negative numbers ( e.g., 3 – 4 = ⁻1). Simple unit fractions are the next group of numbers that are met i.e., {1/2, 1/3, 1/4, 1/5 ... }, then other fractions (e.g., 3/4, 4/9, 7/2, 3/100, ⁻1/2 etc.) which are known as the rational numbers (Q). We next move onto decimal numbers (such as 0.3, 0.32, ⁻2.7). These can be called decimal fractions, because they can be written in a fractional form (e.g., 3/10, 32/100, ⁻27/10). These EXPAND to the real numbers (R), which include irrational numbers such as π, √2. An irrational number cannot be represented as a fraction (i.e., a rational number). π can be represented with numerals, i.e., 3.14159265 ... ; however the digits go on infinitely but there is no pattern to them.

The length of a rectangle is twice its breadth and its area is 288cm?.. Find the dimensions of the rectangle.

Answer»

Answer:

Length=24cm ,BREADTH=12cm..

Step-by-step explanation:

Let it's breadth be x.cm

Then length=2X.cm

AREA=length×breadth

=2x ×x

=2x²cm²

But,area according to question

=288cm²

2x²=288

x²=288/2

x²=144

x=√144

x=12cm

Hence,Breadth=12cm

Length=2x=2×12=24cm
