11.	5.Sum of two numbers is 95. If one exceeds the other by 3, find the numbers.
Answer» Answer: Let the ONE number be x and the other number be y. It is given that the sum of the numbers is 95, therefore, we have: x+y=95....(1) It is also given that one number exceeds the other by 3 which MEANS: x=y+3 ⇒x−y=3....(2) Now, we add equations 1 and 2 as follows: x+y+x−y=95+3 ⇒(x+x)+(y−y)=98 ⇒2x=98 ⇒x= 2 98 ⇒x=49 Now, substitute the value of x in EQUATION 2 to find the value of y as shown below: x−y=3 ⇒49−y=3 ⇒y=49−3 ⇒y=46 Therefore, the two numbers are x=49 and y=46 and the product of the numbers is: x×y=49×46=2254. Hence, the product of the numbers is 2254

5.Sum of two numbers is 95. If one exceeds the other by 3, find the numbers.

Answer»

Answer:

Let the ONE number be x and the other number be y.

It is given that the sum of the numbers is 95, therefore, we have:

x+y=95....(1)

It is also given that one number exceeds the other by 3 which MEANS:

x=y+3

⇒x−y=3....(2)

Now, we add equations 1 and 2 as follows:

x+y+x−y=95+3

⇒(x+x)+(y−y)=98

⇒2x=98

⇒x=

2

98

⇒x=49

Now, substitute the value of x in EQUATION 2 to find the value of y as shown below:

x−y=3

⇒49−y=3

⇒y=49−3

⇒y=46

Therefore, the two numbers are x=49 and y=46 and the product of the numbers is:

x×y=49×46=2254.

Hence, the product of the numbers is 2254

A fruit _ seller bought banana at the rate of 3 for rs 8 and sold them 2 at the rate of 2 for rs.7 find his gain or loss percent!... don't spamexplain.please.

Answer»

Answer:

C.p of 3 BANANA = 8

s.p of 2 banana = 7

so,

cp of 1 banana = 8/3

sp of 1 banana = 7/2

GAIN = s.p - c.p

=

$\frac{7}{2} - \frac{8}{3} \\ \\ \frac{21 - 16}{6} = \frac{5}{6} \\ \\$

gain% =

$\frac{gain \times 100}{cp}$

$\frac{ \frac{5}{6} \times 100}{ { \frac{8}{3} } } \\ \\ = \frac{500 }{6 } \times \frac{3}{8} \\ \\ = \frac{500}{16} \\ = 31.25\%$

$\huge\boxed{\fcolorbox{red}{pink}{❥Qᴜᴇsᴛɪᴏɴ}}$

The sum of three consitutive even number is 150 FIND the numbers ?

$\huge\boxed{\fcolorbox{red}{pink}{❥Answer }}$

Let the lowest number by y

The 3 numbers are then y, y+2, and y+4

Addding the three together

y+y+2+y+4

= 3y+6

But 3y+6=150

3y+6=150

3y=150-6=144

y=144/3

y=48

So the numbers are 48,49,50

More to KNOW :

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.

For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.

If N is an INTEGER, (n + 1) and (n + 2) will be the NEXT two consecutive integers.

For example, let n be 1. We find its consecutive integers as (1 + 1) and (1 + 2), or 2 and 3

Write the answer of this question 15:20::3:x find x

Answer»

Here is your ANSWER!

Question:

write the answer of this question

15:20::3:X find x

Answer:

$4$

Step-by-step explanation:

$\frac{15}{20} = \frac{3}{x}$

= $15x = 20$ × $3$

= $15x = 60$

$x =$ $\frac{60}{15}$

$x = 4$

To cross-check, we have to cross-multiply.

$\frac{15}{20}$ × $\frac{3}{4}$

$15$ × $4 = 20$ × $3$

$60 = 60$

Hence, verified.

Hope it HELPS!!
