Question

the ink in a pen lasts for 12 pages where each page has 32 lines

Answer 1

$It \:is \: given \:that \\Ink \:in \:a \:pen \:lasts \:12 \:pages \\and \\Number \:of \: lines \: each\:page \:has = 32$

$Total \: number \: lines \: in \: 12 \:pages \\= 12 \times 32 \\= 384$

Therefore.,

$\red {Total \: number \: lines \: in \: 12 \:pages}\green {= 384}$

Answer 2

Let's assume number of words per line = 100

• total words = 12 ×32 ×100

• total words = 48 × 80 ×x where x is the number of pages.

$\red{Ink \: is \: half \: the \: pen.}$

Now ,

12 ×32 × 100 / 2 = 19200

x = 19200 / (48* 80) = 5
