Question

At a particular time, the shadow of a pole and tower are respectively 20m and 30m. If the height of the tower is 48m, find the height of the pole.

Answer 1

Answer:32 m

Step-by-step explanation:as if we divide 30 and 48 by 3- 10 and 16

It means, if hieght is 16 m then shadow will be 10 m

So if shadow is 20 m so hieght would be 16*3=32m

Answer 2

Answer:

$let \: the \: height \: of \: pole \: be \: : h \\ \frac{height\: of \: tower}{height \: of \: pole} \\ = \frac{length \: of \: towers \: shadow}{lenght \: of \: poles \: shadow} \\ \frac{48}{h} = \frac{30}{20} \\ h = 48 \times \frac{20}{30} \\ = 32$
