Question

Find the total money Rs. 'M' in a purse, if the purse contains $2x$ notes of $Rs.5$ each, $3y$ notes of $Rs.2$ each, $6z$ coins of $Re.1$ each and $8r$ coins of $50$ paise each.

• A. $M=Rs.(10x+6y+6z+4r)$
• B. $M=Rs.(6x+10y+4z+6r)$
• C. $M=Rs.(10x-6y+6z+4r)$
• D. $M=Rs.(6x-10y+4z+6r)$

Answer 1

The correct option is A $M=Rs.(10x+6y+6z+4r)$

$2x$ notes of $Rs.5$ each = Rs. $5\left(2x\right)$ = $Rs.10x$

$3y$ notes of $Rs.2$ each = Rs. $2\left(3y\right)$ = $Rs.6y$

$6z$ coins of $Rs.1$ each = Rs. $1\left(6z\right)$ = $Rs.6z$

$8r$ coins of $50$ paise each = Rs. $0.50\left(8r\right)$ = $Rs.4r$

Total amount $M=10x+6y+6z+4r$
