Ram has twice the amount of money that Shyam has. If Shyam gets Rs. 20, he will have Rs. 30 less than Ram. How much money does Ram have?


ARs. 100

BRs. 200

CRs. 140

DNone of these

Answer: Option A

Explanation:

Lets assume amount of money Ram and Shyam be Rs. x and Rs. y respectively.

Given that Ram has twice the amount of money that Shaym has => x = 2y.

If Shyam gets Rs.20 then Shyam amount of money = y+20.
Then he will have Rs.30 less than Ram => x-30 = y+20
=> 2y -30 = y+20
=> y = Rs. 50;
=> x =2y = 2* 50 = Rs.100

So Amount of money Ram has (x) is Rs. 100

Choose the correct option.

A man can hit a target once in 3 shots. If he fires 3 shots in succession, find the probability that he will hit his target.


A2/9

B19/27

C5/9

D1/27

Answer: Option B

Explanation:

Probability of hitting the target= (1- probability of not hitting the target)
if he hits once every 3 balls,
probability of hitting = 1/3,
So, probability of not hitting=2/3
probability of not hitting the target all three times= (2/3)* (2/3)* (2/3)
Probability of hitting target = 1 -(2/3)^3 = 19/27

Total 100 members are writing exam. In the 48 members are writing first exam. 45 members are writing second exam. 38 members are writing third exam. 5 members are writing all the three exams. How many members are writing 2 exams?


A18

B6

C20

D21

Answer: Option D

Explanation:

Total number of exams written by 100 students = 48 + 45 + 38 = 131
Now let us say x members are writing only 1 exam, y members are writing only 2 exams, z members are writing only 3 exams.
Therefore, x + 2y + 3z = 131
also, x + y + z = 100.
Given that z = 5. So x + 2y = 116 and x + y = 95.
Solving we get y = 21.
So, 21 members are writing exactly 2 exams.
