Explanation:Given 16 floors building which each floor has 12000 sq.ft
so total space = 16*12000 is 192000.
11 floors are given for rent so 11*12000 ie 132000
so the unrented floor space is (192000-132000) = 60000

Even then a profit of 8000 is made.
Let N be no. of copies.
Therefore,
(N*0.2)+8000=15000
N*0.20=7000
N=35000
So 35000 copies sold

8. A train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?
Answer: 240 m
Explanation:Speed = (54 x 5 /18) m/sec = 15 m/sec.
Length of the train = (15 x 20)m = 300 m.
Let the length of the platform be x metres.
So (x + 300)/36 = 15
x + 300 = 540
=> x = 240 m.

10. Kartik rides a bicycle 8 km/hr and reaches his school 2.5 minutes late. The next day he increases his speed to 10 km/hr and reaches the school 5 minutes early. How far is the school from his house?
Answer: 5 km
Explanation:Let the total distance be d km. We have speed = 8km/hr and 10km/hr.
We know, time (t) = distance (d)/speed (s).
= > t = d/8 (for the first day)
=> t = d/10 (for the second day)
Difference between the time taken on first day and second day is 2.5 + 5 = 7.5 mins.
Therefore, (d/8) - (d/10) = 7.5/60. (7.5 mins converted to hours)
=> (10d - 8d)/80 = 75/600
=> d = (75 x 80)/1200.
=> d = 5 kms.
Therefore, the distance between his school and house 5 km.
