• B. c. $5x+2x=70$d. $10,10$

Answer 1

Given : There are $x$ number of $₹5$ each, so the total worth $=5x$

There are $x$ number of $₹2$ each, so the total worth $=2x$

It is given that the total worth is $₹70$.

So, equation formed is ;

$\Rightarrow 5x+2x=70$

$\Rightarrow$ $7x=70$

$\Rightarrow$ $x=10$

Hence, there are $10$, $5$ rupee coins and $10$, $2$ rupee coins.
