Question

Solve for u : u/0.9 = 35/21A- 0.5B- 1.3 C- 1.5D- 17

Answer 1

Consider the given expression as,

`(u)/(0.9)=(35)/(21)`

Multiply both sides by 0.9,

`\begin{gathered} (u)/(0.9)*0.9=(35)/(21)*0.9 \\ u=(5)/(3)*0.9 \\ u=(5)/(1)*0.3 \\ u=1.5 \end{gathered}`

Thus, the value of 'u' is 1.5

Therefore, option C is the correct choice.
