g


Answer:_______________




 

1)  

5 similar watches weigh 400 g more than 2 similar clocks.
If one watch weighs 160 g, how heavy is one clock

Answer: 200 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 160 g x 5 = 800 g
Step 2: Weight of 2 clocks → 800 g - 400 g = 400 g
Step 3: Weight of 1 clock → 400 g ÷ 2 = 200 g

One clock is 200 g.



2)  

5 similar watches weigh 340 g more than 2 similar clocks.
If one watch weighs 200 g, how heavy is one clock

Answer: 330 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 200 g x 5 = 1000 g
Step 2: Weight of 2 clocks → 1000 g - 340 g = 660 g
Step 3: Weight of 1 clock → 660 g ÷ 2 = 330 g

One clock is 330 g.



3)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 150 g, how heavy is one clock

Answer: 215 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 150 g x 5 = 750 g
Step 2: Weight of 2 clocks → 750 g - 320 g = 430 g
Step 3: Weight of 1 clock → 430 g ÷ 2 = 215 g

One clock is 215 g.



4)  

5 similar watches weigh 370 g more than 2 similar clocks.
If one watch weighs 230 g, how heavy is one clock

Answer: 390 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 230 g x 5 = 1150 g
Step 2: Weight of 2 clocks → 1150 g - 370 g = 780 g
Step 3: Weight of 1 clock → 780 g ÷ 2 = 390 g

One clock is 390 g.



5)  

5 similar watches weigh 280 g more than 2 similar clocks.
If one watch weighs 110 g, how heavy is one clock

Answer: 135 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 110 g x 5 = 550 g
Step 2: Weight of 2 clocks → 550 g - 280 g = 270 g
Step 3: Weight of 1 clock → 270 g ÷ 2 = 135 g

One clock is 135 g.



6)  

5 similar watches weigh 340 g more than 2 similar clocks.
If one watch weighs 190 g, how heavy is one clock

Answer: 305 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 190 g x 5 = 950 g
Step 2: Weight of 2 clocks → 950 g - 340 g = 610 g
Step 3: Weight of 1 clock → 610 g ÷ 2 = 305 g

One clock is 305 g.



7)  

5 similar watches weigh 250 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 300 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 250 g = 600 g
Step 3: Weight of 1 clock → 600 g ÷ 2 = 300 g

One clock is 300 g.



8)  

5 similar watches weigh 340 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 130 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 340 g = 260 g
Step 3: Weight of 1 clock → 260 g ÷ 2 = 130 g

One clock is 130 g.



9)  

5 similar watches weigh 390 g more than 2 similar clocks.
If one watch weighs 150 g, how heavy is one clock

Answer: 180 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 150 g x 5 = 750 g
Step 2: Weight of 2 clocks → 750 g - 390 g = 360 g
Step 3: Weight of 1 clock → 360 g ÷ 2 = 180 g

One clock is 180 g.



10)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 220 g, how heavy is one clock

Answer: 390 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 220 g x 5 = 1100 g
Step 2: Weight of 2 clocks → 1100 g - 320 g = 780 g
Step 3: Weight of 1 clock → 780 g ÷ 2 = 390 g

One clock is 390 g.
