Answer 1

$\boxed{\bold{\large{Answer:}}}$

$\text{Let\:50\:paisa\:Coins\:be\:x\:=\:50x}$

$\text{So,\:The\:70\:rupee\:Coins\:will\:be\:70\:-\:x\:=\:100(70\:-\:x)...... (i)}$

$\text{45\:rupees\:will\:be\:equal\:to\:4500\:Paisa......(ii)}$

$\text{From\:(i)\:and\:(ii)\:we\:get,}$

Answer 2

HEY MATE HERE IS YOUR ANSWER
$\rule {144} {4}$

Given :-

a woman has only 50 paise and one rupee coin in her purse and she has 70 coins totalling rupees 45.

_____________↙️_______________

Let 50 paise coins be x.

Therefore,

$\bold {50 \: becomes \: 50x}$

Therefore,

70 ₹ coin will be 70 - x= 100(70 - x) - - - - - (1)




45 rupees will be as a 4500 paisa - - - - - (2)

$\rule {146}{2}$


$\bold {From \: Equations \: 1 \: And \: 2}$

We get,

➡️ 50x + 100(70 - x) = 45000

➡️ 50x + 70000 - 100x = 4500

=> - 50x = -2500

➖ from ➖ will be cut

➡️ 50x = 2500

➡️ x = 2500/ 25 = 50

Therefore,

She has 50 coins of 50 paise.

$\rule {135} {2}$
