Solution

The correct option is D 9
The price for $3$ oranges is Rs $3 x$ . Rina had spent Rs $(6 x + 4 y)$ . So, the total amount spent is Rs $(6 x + 4 y + 3 x)$ = Rs $(9 x + 4 y)$ . Hence, the coefficient of $x$ is $9$ .

The correct option is D 9The price for 3 oranges is Rs 3x. Rina had spent Rs (6x+4y). So, the total amount spent is Rs (6x+4y+3x) = Rs (9x+4y). Hence, the coefficient of x is 9.
