Answers & Solutions:
1) Answer (C)
Let total number of members be T.
The number of married number if percent is 28% = .28T
Hence, percent of unmarried members = (100-28)%=72%
And the number = .72T
The ratio of married to unmarried= .28/.72 = $\frac{7}{18}$
2) Answer (E)
As we are not given any absolute figures, a unique value of A’s salary cannot be determined.
3) Answer (E)
Amount taken by M = $\frac{3}{4}*44352$ = Rs 33264
Remaining amount = 44352 – 33264 = Rs 11088
Amount taken by N = $\frac{1}{6}*11088$ = Rs 1848
Remaining amount = 11088 – 1848 = Rs 9240
O gets $\frac{3}{7}$th share of Rs 9240 => $\frac{3}{7}$*9240 = Rs 3960
4) Answer (B)
Since Anil’s age is 1.5 times the Purvi’s age,
Purvi’s age = x
Anil’s age = 1.5x
$\frac{1.5x+8}{x+8} = \frac{25}{18}$
(1.5x+8)18 = 25(x+8)
27x+144 = 25x+200
2x = 56
x = 28
5) Answer (A)
Since the amount reinvested is in the ratio 6:7,
the amount reinvested in equity is $\frac{7}{6+7}$ of total amount.
$\frac{7}{13}$ x = 94500
x = 94500*13/7
Since there was a 30% profit on this amount,
Original amount = (94500*13)/(7*1.3) = 135000
Amount invested in equity =$\frac{5}{5+4}*135000$ = 75000
6) Answer (C)
Profit = 0.2 CP
Profit = SP – CP
1.2CP = SP
Hence, CP = (SP/1.2) = 75.6/1.2 = 63
Now, let the cost of type 1 rice is T1 and cost of type 2 be T2.
63 = $\frac{T1 + 3T2}{4}$
= (75 + 3*x)/4
x = 59
Therefore, cost of type 2 price is 59.
7) Answer (B)
Let the numerator and denominator be x and y.
(x/y) = (16/21)
Now, if the first number is increased by 30% and the second number is decreased by 20% then the ratio is $\frac{1.3*16}{0.8*21}$
Which equals $\frac{208}{168}$
Which equals $\frac{26}{21}$
Option B is the correct answer.
8) Answer (C)
Let Ravi’s age be x and Simar’s be y.
x=y+4
After 4 years,
(x+4)/(y+4) = 9/8
8x-9y = 4
After solving we get Ravi’s age be 32 years.
15 years before his age is 32-17=17 years.
9) Answer (D)
Let the earnings of A and B be 8k and 9k respectively.
New earnings of A = 150/100 * 8k = 12k
New earnings of B = 3/4 * 9k = 6.75k
So, 12k : 6.75k = 16 : 9
But, from this equation, we cannot determine the value of k.
So, option d) is the correct answer.
10) Answer (A)
Let the odd number be O and even number be E.
Given that $ \frac{O}{E}$ = 0.625 = $\frac{625}{1000}$ = $\frac{5}{8}$
