Q2.Two numbers are in the ratio 3 : 5, If 9 be subtracted from each, then they are in the ratio 12 : 23. The second number is:
- 52
- 53
- 54
- 55
Solution
:
69x – 207 = 60x – 108
9x = 99 x = 11
Second number is 5x i.e. 55
Q3. What is the ratio whose terms differ by 40 and the measure of which is 2/7?
- 16 : 56
- 14 : 56
- 15 : 56
- 16 : 72
Solution
: 2/7 diff = (7 – 2) = 5
Difference = 40 40/5 = 8
Multiplying numerator & denominator by 8
16/56
Q4. A sum of Rs.7000 is divided among A, B, C, in such a way that shares of A and B are in the ratio 2 : 3 and those of B and C are in the ratio 4 : 5. The amount received by C is:
- Rs. 2600
- Rs. 2800
- Rs. 3000
- Rs. 3900
Solution
: A : B = 2 : 3 B : C = 4 : 5
A : B : C = 8 : 12 : 15
7000 = A + B + C =
+ C = 35C/15
7000 = 7/3 C C = 3000
Q5. If A’s money is to B’s money as 4 : 5 and B’s money is to C’s money as 2 : 3 and A has Rs.800, then C has:
- Rs. 1000
- Rs.1200
- Rs.1500
- Rs.2000
Solution
: A : B = 4 : 5 B : C = 2 : 3
A = 800
B = 5/4 800 = 1000
C = 3/2 1000 = 1500
Q6. If X and Y shared Rs. 1100 in the ratio 1 : 10, how much did X get?
- Rs. 99
- Rs.100
- Rs.101
- Rs.110
Solution
: x : y = 1 : 10 = 100 : 1000
: x : y = 1 : 10 = 100 : 1000
Q7. If a : b = 3 : 4, then (6a + b) : (4a + 5b) is
- 1 : 2
- 3 : 5
- 11 : 8
- 11 : 16
Solution
: a : b = 3 : 4
Q8. If A : B = 3 : 4, B : C = 5 : 6 and D = 11 : 9, then A : D is:
- 50 : 60
- 55 : 72
- 60 : 70
- 65 : 75
Solution
: A/C = (A/B) x (B/C) = 3/4 x 5/6 = 15/24
A/D = (A/C) x (C/D) = 15/24 x 11/9 = 55/72
A : D = 55 : 72
Q9.If A : B = 5 : 7 and B : C = 6 : 11, then A : B : C is:
- 55 : 77 : 66
- 30 : 42 : 77
- 35 : 49 : 42
- None of these
Solution
A : B = 5 : 7 B : C = 6 : 11
A : B : C = 5 x 6 : 7 x 6 : 11 x 7 = 30 : 42 : 77
Q10. lf A : B = 8 : 15, B : C = 5 : 8 and C : D = 4 : 5, then A : D is equal to :
- 2 : 7
- 4 : 15
- 8 : 15
- 15 : 4
Solution
: A : B = 8 : 15 B : C = 5 : 8
C : D = 4 : 5
A : C = A : B x B : C = 
A : D =
