A ramp makes an angle of 60 degrees with the ground. If I walk up 200 metres on the ramp, at what height from the ground will I reach?
A100 m
B200 m
C150 m
D173.2 m
E120 m
Answer: Option D
Explanation:Since 200 metres is travelled along the ramp,
Hypotenuse =200
Angle given = 60 degree
Therefore applying trigonometry,
sine x = Hypotenuse/height [Formula]
sin 60 = 200/h
Therefore, h=(sqrt(3)/2)*200=173.2 metres.

In how many possible ways can you write 1800 as a product of 3 positive integers a,b and c.
A340
B360
C260
D45
Answer: Option B
Explanation:Formula (n+r-1) C (r-1)
where n=power
r=no of integers
1800=3^2*5^2*2^3
hence (2+3-1) C (3-1)=6
(2+3-1) C (3-1)=6
(3+3-1) C (3-1)=10
=> 6*6*10=360

An ant smartly moves across a staircase taking the shortest distance. Calculate the distance it takes to reach top to B from A. Given that staircase consist of 2 steps. It also known that the length,breadth and height is 6cm,2cm and 1cm respectively.
A3
B6 _/3
C6 _/2
DNone of these
Answer: Option C
Explanation:Assume there is a staircase with 2 steps length = 6cm and breadth and height are 1 and 2
so the shortest distance is from left end of the 1st step to right end of the 2nd step which forms a right angled triangle, triangle side are AB, AC and BC.
By using pythagoras theorem,
AC^2 = AB^2+BC^2
AC^2 = 6^2+(2+1+2+1)^2 [height + breath of 2 steps]
AC^2 = 36+36
AC = 6 _/ 2

Find the last digit of the following expression:
4+9^2+4^3+9^4+4^5+9^6+....+9^100
A0
B1
C3
D7
ENone of these
Answer: Option A
Explanation:Last digit of 4^1 = 4 ; 4^3 = 4 ; 4^5= 4....
So, 99 = 1+(n-1)*2 n = 50 i.e. 4+4+4....50 times i.e. 4*50 = 200 (last digit 0)
Similarly, last digit of 9^2=1 ; 9^4 = 1....
So, 100 = 2+(n-1)*2 n=50 i.e. 9+9+9+....50 times i.e. 9*50 = 450 (last digit 0)
So, 200+450 = 650 i.e. last digit is '0'.

Two cards are drawn at random from an ordinary pack of cards . Find the probability that they will consist of a king
A1/52
B1/1326
C1/221
DNone of these
Answer: Option C
Explanation:Sample space is 50C2 which is equal to 1326. Events of getting 2 kings out of 4 is 4C2 which is equals to 6. So probability of getting two kings is 6/1326 = 1/221.
