A train 110 meters long passses telegraph pole in 3 seconds. How long will it take to cross a platform 165 meters long?

Select the correct answer

4 sec 4.5 sec 7.5 sec 10 sec

Solution!
Length of the train = L1 = 110m
Time = t1 = 3s

v = L1/t
v = 110/3

Length of the platform = L2 = 165m

t2 = (L1+L2)/v
By putting values
t2 = (110+165)*(3/110)
t2 = 7.5s

Hence it will take 7.5 seconds to cross the platform..

Solution!
Let cost price of the car is x.
10% of x = 10x/100 = x/10

Now
495000 - (x/10) = x
4950000 - x = 10x
4950000 = 11x
x = 450000.

Question No 14

Solution!
Let Ronit's present age be x years. Then, father's present age =(x + 3x) years

x = 8

Hence, required ratio = (4x+16)/(x+160)
= 48/24 = 2.
