Question

Karan keeps his toys on a weighing machine (as shown in picture). All the levers of the weighing machine are in a balanced position. If the weight of the elephant toy is 2kg, what is the weight of the tiger toy​

Answer 1

Solution :-

Let ,

• Fish = F
• Tiger = T
• Teddy = D
• Elephant = E .

so,

from image we have given that,

• F + T + D = E --------- Eqn.(1)
• F = T + D --------- Eqn.(2)
• T = D --------- Eqn.(3)

putting value of Eqn.(3) in Eqn.(1),

→ F = T + T

→ F = 2T --------- Eqn.(4)

now, putting value of Eqn.(4) and Eqn.(3) in Eqn.(1),

→ F + T + D = E

→ 2T + T + T = E

→ 4T = E

given that, weight of elephant toy is 2kg .

therefore,

→ 4T = 2kg

→ T = (2/4)

→ T = (1/2) kg = 500 gm. (Ans.)
