Here to convert 0.125 into %

First convert to fractio

Multiply and divide by 1000

=>  0 . 125 x 1000 1000 = 125 1000 = 1 8

=> Now,  $$\begin{gathered} in percentage \\ 1 8 x 100 = 12 . 5 % \end{gathered}$$

We know that 40% =  2 5

40% of 265 + 35% of 180 = 50% ?

2 5 x 265 + 35% of 180 = 50% ?

We know that (35% of 180 = 180% of 35) & 180% =  9 5

2 5 x 265 +  9 5 x 35 = 50% ?

106 + 63 = 50% ?

?= 2 x 169 = 338.

Given in municipality election 54% votes have won by 1080

Let the total number of votes be x.

  54 x 100 - 46 x 100 = 1080

8x = 108000

x = 13,500

Therefore, total number of votes = 13,500.

Let the total number of valid votes be 'V'.

70% of V = 70/100 x V = 7V/10

Number of votes secured by the other candidate = V - 7V/100 = 3V/10

Given, 7V/10 - 3V/10 = 172 => 4V/10 = 172

=> 4V = 1720 => V = 430.

Let the number be n. Then,

50% of n - 35% of n = 24

50/100 n - 35/100 n = 24

n = (24 x 100)/15 = 160.

Let the number be 'N'
Given N + 30N/100 = 390
=> 130N/100 = 390
=> N = 390 x 10/13
=> N = 300.

y=100 x=130

130---------30
100---------? => 23 1/3%

Let the total number of pages in the book be 'x'.

From given data,

2x/5 + 34x/100 + 52 + 52 = x

 => 40x + 34x + 10400 = 100x

 => 26x = 10400

 => x = 400.

 Hence, total pages in the book are 400.

Let marks obtained by N = x

M's marks = 0.80x

L's marks = 1.25 (0.80x)

K's marks = (0.90) (1.25) (0.80x)

= 0.9x

But 0.9x = 360 ? x = 400

Percentage of Marks obtained by N

= 400 x 100/500 = 80%

Let Veena's weight = 1 kg

Sana's weight = 2 kg

Sneha's weight = 1.4 kg

Rina's weight = 1.8 kg

Now,according to the given data in the question,

1 . 8 x 100 = 1 . 4

x = 1 . 4 × 100 1 . 8 = 700 9 = 77 7 9.
