Answer:1by2

Step-by-step explanation:

Answer 2

SOLUTION

Let Re. 1 coins be x

So, 50 paise coin will be 70-x.

Total Money of Re 1 coins= 1x

Total Money of 50 paise or 1/2rupee= 70-x/2

A/q

$= > \frac{x + (70 - x)}{2} = 45 \\ \\ = > \frac{x + 35 -x}{2} = 45 \\ \\ = > \frac{x}{2} = 45 - 35 \\ \\ = > \frac{x}{2} = 10 \\ \\ = > x = 20$

So, 1 coin = 20

50 paise coin= 70-20

50 paise coin=70-20=) 50.

hope it helps ☺️
