the first day anna read a quarter of the book. on the second day she read a third of the remainder. noticed that after two days
Misha Larkins [42]

Answer:

160 pages

Explanation:

Day\ 1 = \frac{1}{4}

Day\ 2 = \frac{1}{3}Remainder

Left = 80

Required

The number of pages

Let the number of pages be x.

So, on day 1; we have:

Day\ 1 = \frac{1}{4}x

After day 1, there are:\frac{3}{4}x left ----------------- i.e x - 1/4x

On day 2, we have:

Day\ 2 = \frac{1}{3} * \frac{3}{4}x

Day\ 2 = \frac{1}{4}x

At this point, we have:

Day\ 1 = \frac{1}{4}x

Day\ 2 = \frac{1}{4}x

Left = 80 ---- pages left

The summation of all must equal x, the book pages

Day\ 1 + Day\ 2 + Left = Total\\

\frac{1}{4}x + \frac{1}{4}x+ 80= x

Simplify the left-hand side

\frac{1}{2}x+ 80= x

Collect like terms

x - \frac{1}{2}x= 80

Simplify

\frac{2-1}{2}x= 80

\frac{1}{2}x= 80

Multiply by 2

2 * \frac{1}{2}x= 80*2

x = 160
