A). 8750

B). 133750

C). 116250

D). 125000

View Answer

Correct Answer: 133750

In 2013, the population of a town=1,25,000

7% increased in the next Year

In 2014, the population of the town = 1,25,000\( \left( 1 + \frac{7}{100} \right) \)

=1,25,000\( \left( 1 + \frac{107}{100} \right) \)

=1,250 X 107 = 1,33,750

44). A horse and two cows together cost Rs.680. If a horse cost Rs.80 more than a cow then the ratio of cost of horse and cow is

A). 7 : 5

B). 5 : 7

C). 8 : 9

D). 9 : 8

View Answer

Correct Answer: 7 : 5

Let the cost of a horse be Rs.x.
Let the cost of two cows be Rs.2y

x + 27 = Rs.680.... (1)
x - y =Rs.80 ... (2)
.................................

3y = Rs. 600

So y = Rs.200
x - 200 = 80
x = 280
x : y = 280 : 200
= 7 : 5

45). \( \large\frac{1}{4} of \frac{3}{5} of \frac{6}{5} \) of a number is 54. Then the number is

A). 280

B). 300

C). 320

D). 350

46). If \( \large A:B = \frac{1}{3}:\frac{4}{9} \),\( \large B:C = \frac{5}{6}:\frac{7}{12} \), \( \large C:D = \frac{2}{7}:\frac{5}{14} \) then A : B : C : D is

A). 40:28:35:30

B). 30:40:28:35

C). 28:30:40:35

D). 35:30:20:40

View Answer

Correct Answer: 30:40:28:35

A : B = \( \large \frac{1}{3} : \frac{4}{9}\)

B : C = \( \large \frac{5}{6} : \frac{7}{12} \)

A : B : C = \( \large \frac{5}{18} : \frac{20}{54}:\frac{7}{27} \)

C : D = \( \large \frac{7}{27} \times \frac{5}{14} \times \frac{7}{2} = \frac{35}{108} \)

A : B : C : D = \( \large \frac{5}{18} : \frac{10}{27} : \frac{7}{27} : \frac{35}{108} \)

=\( \large\frac{30 : 40 : 28 : 35}{108}\)

47). If (3x + 2y) : (3x - 2y) = 5 : 2. Then x:y is

A). 5 : 2

B). 14 : 9

C). 9 : 14

D). 2 : 5
