A
480
B
360
C
270
D

Correct Answer: Option A

The number of students talking English = 4/(4 + 3) x 840 = 480

Question 13
A bag contains 25 paise, 10 paise and 5 paise coins in the ratio 1 : 2 : 3 . If their total value is ₹ 60, then the number of 5 paise coins is ?

A
10
B
50
C
30
D
40
Correct Answer: Option C

Let the number of 25 paise, 10 paise and 5 paise coins be N, 2N and 3N, respectively.
Then ,
N + 2N + 3N = 60
⇒ N = 10
∴ The number of 5 paise coins = 3 x 10 = 30

Question 14
₹ 750 is distributed among A, B and C such that A : B = 5 : 2, B : C = 7 : 13, then what is A's part ?

A
₹ 140
B
₹ 250
C
₹ 260
D
₹ 350
Correct Answer: Option D

A : B = 5 : 2 = 5/2 : 1, B : C = 7 : 13 = 1 : 13/7
A : B : C = 5/2 : 1 : 13/7 = 35 : 14 : 26
∴ A's part = 750 x 35/75 = ₹ 350

Question 15
If 30% of A = 20 % of B, then find the value of A : B ?

A
1 : 3
B
3 : 2
C
3 : 1
D
2 : 3
Correct Answer: Option D

Given that, 30 % of A = 20 % of B
⇒ A/B = 20/30 = 2/3
⇒ A : B = 2 : 3

Question 16
If A = B/4 and B = C/2, then find the value of A : B : C ?

A
8 : 4 : 1
B
4 : 2 : 1
C
1 : 4 : 8
D
1 : 2 : 4
Correct Answer: Option C

Given that, A = B/4
∴ A/B = 1/4 or A : B = 1 : 4
Also, B = C/2 or B/C = 1/2 or B : C = 1 :2
Now, we have A : B = 1 : 4; B : C = 1 : 2
A : B : C = ( 1 x 1 ) : ( 1 x 4 ) : ( 2 x 4 )
= 1 : 4 : 8

Question 17
If P : Q : R = 2 : 3 : 4, then find P/Q : Q/R : R/P ?

A
8 : 9 : 24
B
9 : 8 : 24
C
24 : 8 : 9
D
8 : 24 : 9
Correct Answer: Option A

Given that, P : Q : R = 2 : 3 : 4
Let P = 2K, Q = 3K, R = 4K
∴ P/Q = 2K/3K = 2/3,
   Q/R = 3K/4K = 3/4,
    R/P = 4K/2K = 2/1


∴ P/Q : Q/R : R/P = 2/3 : 3/4 : 2/1
= (2 x 12)/3 : (3 x 12)/ 4 : (2 x 12)/1
= (2 x 4) : (3 x 3) : 24
= 8 : 9 : 24

Question 18
If a/3 = b/8, then ( a + 3 ) : ( b + 8 ) is equal to ?

A
3 : 8
B
8 : 3
C
5 : 8
D
3 : 5
Correct Answer: Option A

Let a/3 = b/8 = K
Then, a = 3K, b = 8K
∴ (a + 3) / (b + 8) = (3K + 3) / (8K + 8)
= [3( K + 1)] / [8(K+1)] = 3/8
∴ ( a + 3 ) : (b + 8) = 3 : 8

Question 19
If xy =36, then which of the following is correct?

A
x : 9 = 4 : y
B
9 : x = 4 : y
C
x :17 = y : 7
D
x : 6 = y : 6
Correct Answer: Option A

xy =36
⇒ xy = 4 x 9
⇒ x/9 = 4/y
∴ x : 9 = 4 : y

Question 20
What sum of money is to divided among 3 persons in the ratio 3 : 4 : 7, so that the second person receives ₹ 12 only ?

A
₹ 21
B
₹ 32
C
₹ 9
D
₹ 42
Correct Answer: Option D

Let required money be ₹ N.
Then,
(4/14) x N = 12
⇒ N = (12 x 14)/4
= ₹ 42
