QUESTION: 1

### A batsman scored 110 runs which included 3 boundaries and 8 sixes. What percent of his total score did he make by running between the wickets?

Solution:

Number of runs made by running:-

110- (3*4+8*6)

= 110- 60

= 50

Therefore, required percentage :-

[( 50/ 110)  * 100] %

=> QUESTION: 2

### If two numbers are respectively 20% and 50% of a 3rd number then what % is the 1st number of the 2nd one?

Solution:

Two numbers are respectively 20% and 50% more than the 3rd number. What percent is the first of the second? Consider 3rd number be 100%.

QUESTION: 3

### If the radius of circle is increased by 110% its area is increased by

Solution:

Option ( c) 341 is correct.

Explanation:-

{Let the initial radius of circle = 10 cm

Then, it's area = π r^ 2

=  π (10) ^2

=  100 π cm square.

Given, (radius is  increased by 110%)

New radius = ( 100+110) % of 10 cm

=> 210% of 10 cm

{ 210 /100 * 10} cm

=> 21 cm

Therefore, area of circle of radius (21) cm

=> π (21) ^2

=>  441 π cm square.

Increase in area=  ( 441 π - 100 π ) cm square.
=> 341 cm square. }

QUESTION: 4

In an election between two candidates, one got 55% of the total valid votes, 20% of the votes were invalid. If the total number of votes was 7500, the number of valid votes that the other candidate got, was:

Solution:

= 80% of 7500
= 6000
∴ Valid votes polled by other candidate
= 45% of 6000
=  45100×600045100×6000 = 2700

QUESTION: 5

In an exam 80% of the students passed in Eng, 85% in Math and 75% in both. if 40 students failed in both subjects, the total number of students is?

Solution:

Let n(A) = no. of students pass in english
n(B) = no. of students pass in math
n(A U B) = no. of students pass in either math or english
n(A ∩ B) = no.of students pass in both math and english
let x are no. of students
⇒ n(A U B) = n(A) + n(B) - n(A ∩ B)
= 80x/100 + 85x/100 - 75x/100
= 90x/100
no. of students fail in both either math or english = x - n(A U B)

⇒ 40 = x - 90x/100

⇒ 40 =  x/10

⇒  x = 400
total no. of students = 400

QUESTION: 8

In an examination, Summit got 30% marks and failed by 15 marks. In the same examination, Rohit got 40% marks, which is 35 marks more than the pass marks. Then what is the total marks in the examination?

Solution:

The correct option is A.
Let the total marks be x.
Sumit got = 30% of x
= 0.3x
Passing marks = 0.3x+15

Rohit got = 40% of x
= 0.4x
Passing marks = 0.4x - 35

Equating both passing marks , we get
0.3x+15 = 0.4x - 35
50 = 0.1x
x = 500

So total fail percentage would be
42+52-17 ( because we have counted the 17 % 2 times)
=> 77 % who have failed SO the percentage passing in both would be
100-77= 23%

Depreciation - 10% of present value annually
After one year value of machine will be =  4000 - 400(10% of 4000) = 3600
After 2nd year value of machine will be = 3600 - 360(10% of 3600) = 3240
