Question

If the thickness of a pile of 12 cardboards is 35 mm, find the thickness of a pile of 294 cardboards.

Answer 1

Let the fare be Rs x

No of cardboard	12	294
Thickness(mm)	35	x

\(\frac{12}{35}\) = \(\frac{294}{x}\)

On cross multiplication, we get

12x = 35 x 294

x = \(\frac{35\times 294}{12}\) = 857.5

Therefore thickness of the cardboard is 857.5 mm
