Question

A vertical pole of length 3 m casts a shadow of 7 m and a tower casts a shadowof 28 m at a time. The height of tower is 1 point (a) 10 (b) 16 (c) 15 (d) 12m​

Answer 1

Answer:

d) 12m

Step-by-step explanation:

Soln:-

Given,

Length of pole = 3 m

length of shadow = 7m

Now ,

Length of tower= ?

length of shadow = 28 m

we all know that both pole and tower create same shadow st same length . That's why

3:7=x:28

so

3/7 = x/28

=> 3×28= x×7

=> 84= 7x

=> x = 84/7

=> x = 12

so length of tower = 12 m
