Answer 1

Answer:

Apples: 30kg. Bananas: 20kg.

Step-by-step explanation:

Let "x" be number of kgs of banana and "2x" be the number of kgs of apple.

Cost of apple  =  1800

Number of kgs of apple (cost per kg)  =  1800

Number of kgs of apple (2x)  =  1800

Number of kgs of apple  =  1800/2x  =  900/x  -----(1)

Number of kgs of banana (cost per kg)  =  600

Number of kgs of banana (x)  =  600

Number of kgs of apple  =  600/x  -----(2)

(1) + (2)

(900/x) + (600/x)  =  50

(1500 / x)  =  50

x  =  1500/50

x  =  30

By applying x = 30 in (1), we get 

  Number of kgs of apple  =  1800/2(30)  =  30

By applying x = 30 in (2), we get 

  Number of kgs of banana  =  600/30  =  20

Answer 2

Answer:

Number of kgs of apple  =  30

Number of kgs of banana  =  20

Step-by-step explanation:

Let "x" be number of kgs of banana and "2x" be the number of kgs of apple.

Cost of apple  =  1800

Number of kgs of apple (cost per kg)  =  1800

Number of kgs of apple (2x)  =  1800

Number of kgs of apple  =  1800/2x  =  900/x  -----(1)

Number of kgs of banana (cost per kg)  =  600

Number of kgs of banana (x)  =  600

Number of kgs of apple  =  600/x  -----(2)

(1) + (2)

(900/x) + (600/x)  =  50

(1500 / x)  =  50

x  =  1500/50

x  =  30

By applying x = 30 in (1), we get

 Number of kgs of apple  =  1800/2(30)  =  30

By applying x = 30 in (2), we get

 Number of kgs of banana  =  600/30  =  20
