g


Answer:_______________




 

1)  

5 similar watches weigh 250 g more than 2 similar clocks.
If one watch weighs 110 g, how heavy is one clock

Answer: 150 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 110 g x 5 = 550 g
Step 2: Weight of 2 clocks → 550 g - 250 g = 300 g
Step 3: Weight of 1 clock → 300 g ÷ 2 = 150 g

One clock is 150 g.



2)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 110 g, how heavy is one clock

Answer: 115 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 110 g x 5 = 550 g
Step 2: Weight of 2 clocks → 550 g - 320 g = 230 g
Step 3: Weight of 1 clock → 230 g ÷ 2 = 115 g

One clock is 115 g.



3)  

5 similar watches weigh 340 g more than 2 similar clocks.
If one watch weighs 160 g, how heavy is one clock

Answer: 230 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 160 g x 5 = 800 g
Step 2: Weight of 2 clocks → 800 g - 340 g = 460 g
Step 3: Weight of 1 clock → 460 g ÷ 2 = 230 g

One clock is 230 g.



4)  

5 similar watches weigh 400 g more than 2 similar clocks.
If one watch weighs 200 g, how heavy is one clock

Answer: 300 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 200 g x 5 = 1000 g
Step 2: Weight of 2 clocks → 1000 g - 400 g = 600 g
Step 3: Weight of 1 clock → 600 g ÷ 2 = 300 g

One clock is 300 g.



5)  

5 similar watches weigh 330 g more than 2 similar clocks.
If one watch weighs 230 g, how heavy is one clock

Answer: 410 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 230 g x 5 = 1150 g
Step 2: Weight of 2 clocks → 1150 g - 330 g = 820 g
Step 3: Weight of 1 clock → 820 g ÷ 2 = 410 g

One clock is 410 g.



6)  

5 similar watches weigh 390 g more than 2 similar clocks.
If one watch weighs 110 g, how heavy is one clock

Answer: 80 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 110 g x 5 = 550 g
Step 2: Weight of 2 clocks → 550 g - 390 g = 160 g
Step 3: Weight of 1 clock → 160 g ÷ 2 = 80 g

One clock is 80 g.



7)  

5 similar watches weigh 390 g more than 2 similar clocks.
If one watch weighs 160 g, how heavy is one clock

Answer: 205 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 160 g x 5 = 800 g
Step 2: Weight of 2 clocks → 800 g - 390 g = 410 g
Step 3: Weight of 1 clock → 410 g ÷ 2 = 205 g

One clock is 205 g.



8)  

5 similar watches weigh 280 g more than 2 similar clocks.
If one watch weighs 230 g, how heavy is one clock

Answer: 435 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 230 g x 5 = 1150 g
Step 2: Weight of 2 clocks → 1150 g - 280 g = 870 g
Step 3: Weight of 1 clock → 870 g ÷ 2 = 435 g

One clock is 435 g.



9)  

5 similar watches weigh 350 g more than 2 similar clocks.
If one watch weighs 240 g, how heavy is one clock

Answer: 425 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 240 g x 5 = 1200 g
Step 2: Weight of 2 clocks → 1200 g - 350 g = 850 g
Step 3: Weight of 1 clock → 850 g ÷ 2 = 425 g

One clock is 425 g.



10)  

5 similar watches weigh 370 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 240 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 370 g = 480 g
Step 3: Weight of 1 clock → 480 g ÷ 2 = 240 g

One clock is 240 g.
