Question

The two scales below are perfectly balanced cylinder=36then What are the value of rectangular cube cube​

Answer 1

Answer:

It has been given that ∙=3....(1)

(a) 5∗=2Δ+2∙....(2)

(b) 2Δ=2∗+2∙...(3)

(c) 3∗+3∙=3Δ⇒∗+∙=Δ...(4)

By putting equation (4) in (2) we get

5∗=2(∗+∙)+2∙

⇒3∗=4∙

⇒3∗=4×3⋯⋯[from(1)]

⇒∗=4

Putting these values in equation (4) we get

∗+∙=4+3=Δ

⇒Δ=7

∴Δ=7 & ∗=4
