subtracted from 5/2 of a number results in 23. What is the number?

A
-10

B
10

C
12

D
-12

In a test match, Sachin scored twice as many runs as Sehwag. Together, their runs fell two short of a double century. How many runs did Sachin score?

A
66

B

Solution

Let the number of runs scored by Sehwag be 'r'. According to the problem, the number of runs scored by Sachin = 2r Also
r+2r=(2×100−2)⇒ r=66⇒
Sachin's score
Question 4
1 / -0

The sum of three consecutive integers is 75. Which is the largest among them?

A
26

B
25

C
24

D
23

Solution

Let the smallest integer be x−1 . Then the three consecutive integers are x−1, x and x+1.
Their sum = 75
⇒(x−1)+x+(x+1)=75⇒x=25∴ The largest of the numbers
x+1=26
Question 5
1 / -0

Guru is 20 years older than his son. If the sum of their ages is 50 years, how old is his son

A
5 years

B
10 years

C
15 years

D
20 years

Solution

Let the age of the son be 'x' years. So the age of Guru is

x+20

years. Given sum of the ages of Guru and his son= 50 years

⇒ x+x+20=50 ⇒ 2x=50−20⇒x=15
Question 6
1 / -0

If 0.2(2x−1)−0.5(3x−1)=0.4,what is the value of x'?

A
1/11

B
-1/11

C
3/11

D
-3/11

Solution

0.2(2x−1)−0.5(3x−1)=0.4⇒x=−1/11
