2^(2x+4)=16^x2^(2x+4)=(2^4)^x2^(2x+4)=2^(4x)same base; powers should be same2x+4=4x4=4x-2x4=2xx=2Therefore x^3=2^3=8

Option D is correct.

Median = middle term

no of terms = 5

Median = n+1/2 = 5+1/2 = 6/2

= 3rd term

So the median is 5.

86520-02568 = 83952.

Greatest no. ➡86520Smallest no. ➡20568Their difference ➡86520-20568➡65952

Greatest five - digit number by the digits 2,5,0,6,8 is = 86520,Least five - digit number by the digits 2,5,0,6,8 is = 20568,Their difference is = 86520 - 20568, = 65952.

c =30 because three corner's sum 180 in triangle..

c= 30 total angle of triangle is 180 then a+b= 150

c=30 kyuki triangle ke teeno angles ka yog = 180

c=30 because three coroner's sum in 180 in triangle

Angle A=70Angle B=80Angle C=?Now,As we know that Sum of all angles of a triangle is 180Therefore,A+B+C=18070+80+C=180C=180-70-80C=30

Therefore, Angle C=30

Angle A = 70Angle B = 80 Angle C = ?As we know that sum of all angles of a triangle is 180therefore A + B + C = 18070 + 80 + C = 180150 + C = 180C = 180 - 150C = 30

30 degree because angle sum property of triangle states that sum of all 3 angles of triangle is =180 degree

c=30° become a+b+c= 180°a=70°B=80°70°+80°+C= 180°SO C= 30°

A=70,B=80,c=?A+B+c=180,70+80=150,180_150=30

sequel 30 because three corners some 180 degree in triangle

using angle sum property of triangleangle C is 30 degree

X = + 2 - 2 because X + 2 equal to x power 4

angle C= 30 because sum of the triangle angle is 180

the third angle is 30 by applying angle sum property of triangle

c=30 because triangle sum is 180

c=30 because three coroner`s sum in 180 in triangle

30° is the answer of this question

a+b+c=180°70+80+c=180c=180-150c=30°

teeno angles ka yog =180 to c=30 deegri

total angles-180 angle70+angle80 -180-150_30

c is equal to 30 because all sum are 180

angle C= 30 degree because sum of angle of triangle is 180

If angle A=70 and B=80,we know that the sum of angles of a triangle is be 180

triangle c=30 hoga80+50+©=180=180-150=30

c=30 total angle of triangle

since the sum of all angle of triangle is 180, Let third angle be Xthen 70 +80+X=180So,X=30

180-(80+70)=30 degree

c=30 because a+b+c=180so, c=180-a-b =30

180= 70+80+c ? c=30

sum of all angles of triangle is 180°therefore<A+<B+<C=18070+80+<C=180<C=30°

30 degree is correct answer

LA=70, LB=80 WE KNOW THAT LA+LB+LC=180 70+80+LC=180 150+LC=180 LC=180-150=30 SO, LC=30°

c= 30° because there corner is 180°

c=30 right answer hoga

30 is the right answer180-(sum of two angles)

इस त्रिभुज में एंगल C का मान ३० डिग्री होगा

Angle C is 30° C=180-(70+80)C=30°

Let length and breadth of farm be L and B resp.

According to ques, we are given

L = 2B + 10

Area of farm = L * B

or (2B + 10) * B

Area of farm = B * (2B + 10)

Side of square pond is given to be 1/3 of breadth of farm

which is, Side = 1/3 B

Area of square pond will be = Side²

i.e. (1/3 B)²

Area of pond = 1/9 B²

Now it is given, area of farm = 20 x area of pond

So,

B * (2B + 10) = 20 x 1/9 B²

2B + 10 = 20/9 B

20/9 B - 2B = 10

20/9 B - 18/9 B = 10

2/9 B = 10

B = 45m

So, L = 2(45) + 10

L = 100m

and Side = 1/3 (45)

Side = 15m

Therefore, L and B are 45 and 100 of farm, and Side of pond is 15m

AB²=2AC²=AC²+AC²AB² =AC²+BC² { given AC=BC}

Hence ABC is a right angled triangle with angle C = 90° because AB is the longest side and the angle opposite to longest side is largest.

Option (D) is correct.

Mean is always at the centre

largest no. 86520smallest no.02568

their difference is 6885952

largest 7 digit number formed by digits 2, 8, 6, 0, 5 = 8886520

smallest 7 digit number formed by the digits 2, 8, 6, 0, 5 = 2000568

ER. RAVI KUMAR ROY.

difference between both = 8886520 - 2000568 = 6885952 (ANS)

options c is the correct answer.

angle 1 = angle 7 = angle 3 = angle 5 = 75° ( by vertically opposite and alternative angle)angle 1 + angle 8 = 180angle 8 = 180° - 75° = 105°angle 8 = angle 2 = angle 6 = angle 4 = 105° ( by vertically opposite and alternative angle)

(-5/11)^k+2 ÷ (-5/11)^-4k+5= (-5/11)^2k

(-5/11)^[k+2-(-4k+5)] = (-5/11)^2k

(-5/11)^[k+2+4k-5] = (-5/11)^2k

(-5/11)^[5k-3] = (-5/11)^2k

5k - 3 = 2k

5k - 2k = 3

3k = 3

k = 3/3 = 1

so 30 / 100 * 3000= 900

900 is the correct answer

x+x+3 = 95

2x = 92

x = 46

let the two numbers be x and y, y<x.given, x+y=48.......(1) and, x=y+4.........(2)

Now, Putting value of x from (2) in (1)We get, y+4+y=48 or 2y+4=48 or 2y=48-4 or 2y=44 or y=44/2 or y=22.ans..

Continuing....... Putting value of y in (2)We get, x=y+4 x=22+4 x=26

suppose numbers are x and x+15so 2x+15=95so 2x=80 so x=40so numbers are 40 and 55

Let the two numbers be A and B=>A+B=15 .............(1)and 1/A +1/B=3/10⇒(A+B)/AB = 3/10from (1)(A+B)/AB = 15/AB⇒15/AB = 3/10⇒AB = 50 ............(2)solving (1) and (2)A = 10 and B = 5orA = 5 and B = 10

(i) For Malik as Agency :Input Tax (GST on Purchase) = 5% of ₹24500

=24500∗510024500∗5100

= ₹1225

(ii) Output tax (GST on Sale) = 5% of ₹26500

=26500∗510026500∗5100

= ₹1325(iii) GST payable = Output tax – Input tax = 1325 – 1225∴ GST payable =₹100(iv) We know that, CGST and UTGST are similar for the article. The net GST amount isdivided into two equal parts for this.

∴ CGST paid =10021002 =₹50 and ∴ UTGST paid =10021002=₹50

Given:Ratio of two fans = 16:23multiply by common factor xthe prices will be 16x & 23x

AFTER TWO YEARSfirst fan increaed by 10 % = 0.1*16x

price of the fan =16x+1.6x= 17.6x

increase in other fan = Rs. 477price = 23x+477

352x=11(23x+477)

352x=253x+5247352x-253x=5247

99x=5247

x=53Therefore, Price of one fan = 53*16 =Rs. 848

price of second fan = Rs. 1219Like if you find it useful

Let present price of first bicycle be 2xLet present price of second bicycle be 3x

After 2 yearsFirst bicycle price = 2x(1 + 15/100) = 2x*(23/20) = 23x/10Second bicycle price = 3x + 475

Then(23x/10):(3x + 475) = 3:523x/2 = 3(3x + 475)23x = 6(3x + 475)23x - 18x = 28505x = 2850x = 570

Therefore, present price of first bicycle = 2x = 2*570 = 1140
