Answer 1

$\huge\boxed{\fcolorbox{cyan}{Green}{HELLO MATE}}$

$\huge\underline\mathfrak\red{Answer}$

$\huge\boxed{\fcolorbox{cyan}{Orange}{360 pages of book}}$

Solution:

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

Then ,

No. of pages read on Monday = 30% of x

No. of pages read on Tuesday = 50% of x

No. of pages left to be read = 72

Now,

=> Total no. of pages in the book = No. of pages read on Monday + No. of pages read on Tuesday + No. of pages lest to be read .

=> x = (30% of x) + (50% of x) + 72

=> x = (30/100)•x + (50/100)•x + 72

=> x = (3/10)•x + (5/10)•x + 72

=> x = 3x/10 + 5x/10 + 72

=> x = (3x + 5x)/10 + 72

=> x = 8x/10 + 72

=> x - 8x/10 = 72

=> (10x - 8x)/10 = 72

=> 2x/10 = 72

=> x/5 = 72

=> x = 72•5

=> x = 360

Hence,

The total number of pages in the book is 360 .

Answer 2

Answer:

206

Step-by-step explanation:

32% + 7.16% = 39.16%

39.16/100 * (x + 325) = x

39.16x/100 +39.16 * 325/100 = x

39.16*325/100=x-39.16x/100

39.16*325/100=61.84x/100

39.16*325=61.84x

x=39.16*325/61.84

x=3916*325/6184

x=206
