A Parking lot Contains 160 Vehicles. Each Vehicle is either a car or a truck, and each vehicle is either red or green. 70 vehicles are red, and 120 vehicles are cars. If there are 18 green trucks, how many red cars are there?
Total number of Vehicles = 160
There are 70 red vehicles thus rest 90 are green vehicles,
out of which 18 are green trucks then we get,
Green cars = 90 - 18 = 72.
Given, Number of cars = 120.
Then, number of red cars,
= 120 - 72
= 48 Red cars.
A man is 24 years, older than his son. In two years, his age will be twice the age of his son. The present age of his son is ?
Let the present age of his son be X years.
So, present age of his father = X+24 (as he is 24 years older than his son)
After 2 years, father's age become (X+24+2) years and Son's age will be (X+2).
Now, according to question,
X+24+2 = 2*(X +2)
Or, X = 22 years.
Son's present age = 22 years.
M scores more run than N but less than P. Q scores more than N but less than M. Who is the lowest scorer?
M scores more run than N.(M > N) M scores less than P. (P >M >N) Q scores more than N but less than M. So, Sequence of scoring run is P >M>Q>N. So, N is the lowest scorer.

B is twice as old as A but twice younger than F. C is half the age of A but is twice older than d. Who is the second oldest ?
Let, A = x
Then, B = 2x
and, F = 4x
C = x/2
and D = x/4
Thus, The second oldest is B.
Grass in lawn grows equally thick and in a uniform rate. It takes 24 days for 70 cows and 60 days for 30 cows to eat the whole of the grass. How many cows are needed to eat the grass in 96 days?
Let initially X grass was present there,and it is increasing by Y grass per day, then for the first condition We get,
X+24*y = 24*70 ----(1)
For the 2nd condition, we have,
X+60*Y = 60*30----(2) Now, On solving equation (1) and (2), we get
X = 1600 and
Y = 10 /3
X+96*Y = 96 *N -----(3) [N = Number of Cows required]
Putting the values of X and Y in equation (3), We get
N = 20.
