A model of thistower is made such that the ratio between the heightof the actual tower and that of the model is 160:1.Find the height of the model.​

Answer 1

Answer:

6) 72.5 m 7) 1.25 m

Step-by-step explanation:

6) Let H be the height of Qutub minar and h be the height in replica.

given,

h = 1.25 m

Height of actual monument : height of replica = 58 : 1

H: h = 58: 1 => H/h = 58/1

=> H/1.25 = 58/1

=> H = 58 * 1.25 = 72.5 m.

So height of Qutub minar = 72.5 m

7) Let H be the height of tower and h be the height in replica.

given,

H = 200 m

Height of actual tower : height of replica = 160 : 1

H: h = 160: 1  => H/h = 160 /1

=> 200/h = 160/1

=> h = 200 * 1/160 = 5/4 m = 1.25 m  

Height of model = 1.25 m.
