Question

A vertical stick 1.8 m long casts a shadow 45 cm long on the ground. At the same time, what is the length of the shadow of a pole 6 m high?

विकल्प

• 2.4 m

• 1.35 m

• 1.5 m

• 13.5 m

Answer 1

1.5 m

Explanation:

Heights and shadow lengths are proportional. 

Convert 45 cm = 0.45 m.

1.8 : 0.45 = 6 : x

So, `x = (6 xx 0.45)/1.8`

= 1.5 m
