For every two bags of grapes in the market, seven pears are sold. If the total amount of grapes and pears sold at the market is 810, how many were grapes?

Respuesta :

If 2 bags of grap are sold, then pears sold are 7

So pears = [tex]\frac{7}{2}[/tex] × grap bags

Let number of bags of grap be = G

and number of pears be = P

Total amount of grap and pears sold = 810

⇒ P + G = 810

⇒ [tex]\frac{7}{2}  * G + G = 180[/tex]

⇒ 9G = 360

⇒ G = 40

and P = [tex]\frac{7}{2}[/tex] × 40

⇒ P = 140

Hence, 40 bags of grap were sold and 140 pears were sold.
