in a school 25/54 of the students are girls and rest r boys if the number of boys is 2030 find the number of girls

Answer»

Hey!!!!

__________

Fraction of girls = 25/54

Fraction of boys = (54 - 25)/54

=> Fraction of boys = 29/54

let the TOTAL STUDENTS be x

Then

=> (29/54)x = 2030

=> x = 54 x 70

=> x = 3780

Girls = Total Students - Boys

=> Girls = 3780 - 2030

=> Girls = 1750

Thus the total number of girls are 1750.

Unit digit of number raised to another number

Answer»

What is a Units digit?

Units digit of a number is the digit in the one’s PLACE of the number. i.e It is the rightmost digit of the number. For example, the units digit of 243 is 3, the units digit of 39 is 9.

But then what is the units digit of large numbers like 23 to the power 46 or what is the units digit of 2014 to the power of 2014? Here, it is not straight forward to calculate the units digit of these numbers. So lets have a look at the technique to calculate the units digit of large numbers.

Units digit of Large Numbers – number raised to power

One of the ways of FINDING the units digit of a power is by finding the REMAINDER when that number is DIVIDED by 10.
Another general and one of the easier ways to find the units digit of a number in the form
x
y
xy, is done with the help of the following steps:

Identify the units digit in the base ‘x’ and call it say ‘l’. {For example, If x = 24, then the units digit in 24 is 4. Hence l = 4.}
Divide the exponent ‘y’ by 4.
If the exponent y is exactly divisible by 4. i.e, y leaves a remainder 0 when divided by 4. Then,
the units digit of
x
y
xy is 6, if l = 2, 4, 6, 8.
the units digit of
x
y
xy is 1, if l = 3, 7, 9.
If y leaves a non-zero remainder r, when divided by 4 (i.e y = 4k + r). Then,

One of tthe factor of (x-2a)(x-5a)(x-8a)(x-11a)+81a

Answer»

Here, f(X)= x^3 + ax^2- 2x + a + 4
And, G(x)= x + a

We have, x + a = 0
=> x = -a

Now, put the value thus found into f(x) function
f(-a) = (-a)^3 + a(-a)^2 - 2(-a) + a + 4 =0

=> -a^3 + a^3 + 2a + a = -4

=> 3a = -4

=> a = -4/3

2 sets a and b are having 99 elements in common then no of elements common to each of the sets a×b and b×a

Answer»

A and b having 99 ELEMENTS in COMMON .
Then number of elements common to each of the SETS a × b and b × a = 99 × 99
= (99)² = 9801 .

ACTUALLY, you can see choose 99 elements which are common to both a and b in 99 ways SEPARATELY in both the cases .
And when you will multiple these you will get the same number of elements e.g., a × b = (99)² and b × a = (99)²

So, tbe answer should be 99² = 9801

X^2-(2b-1)x+(b^2-b-20)=0

Answer»

Please find below the solution to asked query:

x2 − (2b − 1) x + (b2 − B − 20) = 0
Comparing the above equation with
 Ax2 + Bx + C = 0,
We get,
A = 1
B = −(2b − 1)
C = b2 − b − 20
Now, D = B2 − 4AC
= (2b − 1)2 − 4 (b2 − b − 20)
= 4b2 + 1 − 4b − 4b2 + 4b + 80
= 81 > 0So, the above equation has 2 REAL 
and distinct roots given by,

x = −B + D√2A    or     x = −B − D√2A

⇒ x = 2b − 1 + 92    or     x = 2b − 1 − 92

⇒ x = b + 4    or    x = b − 5

Hope this would clear your doubt.

on a certain sum ,the compound interest in 2years amounts to 4240.if the rates of interest for successive years are 10% and 15% respectively,find the sum.

Answer»

Given

Time=2yr

Amount =4240

Successive RATE of interest =10% and 15%

Let

Sum=100

Interest collected in 1 yr = pxrxt /100

Here r=10% y=1 p=100

Interest (1st yr) = 100x10x1/100

=10

Amount after 1 yr=sum+ interest =100+10

=110

Now 110 is sum for 2ND yr

Interest =pxrxt/100

Here=> p=110, r=15, t=1

Interest =110x15x1/100

=16.5

Amount after 2nd yr=110+16.5

=126.5

But according to the question amount after 2nd yr =4240

1 UNIT assumed =4240/126.5

=31.5177

Sum=100x31.5177

=₹3151.77

Approx =₹3152
