Answer & Explanation

1.(C) The ratio of the no. of boys to the no. of girls = 3 : 5
Sum of the ratios = 3 + 5 = 8
So, the no. of boys in the school = (3 × 720)/8 = 270
And the no. of girls in the school = (5 × 720)/8 = 450
Let the no. of new boys admitted be x, then the no. of boys become (270 + x).
After admitting 18 new girls, the no. of girls become 450 + 18 = 468
According to given description of the problem, (270 + x)/468 = 2/3
or, 3 (270 + x) = 2 x 468
or, 810 + 3x = 936 or, 3x = 126 or, x = 42.
Hence the no. of new boys admitted = 42.

2.(A) 7(x+2p)^2+5p^2= 35px+117 p^2
7x^2+33p^2+28px = 35px+ 117 p^2
x^2-px+12p^2 = 0
on solving x= 4p,-3p

3.(A) Interest = 20000[(1+4/100)^2-1]= 1632
Efeective rate of interst = 1632/20000*100=  8.16%

4.(B) Work done by 3 men in 2 days = (1/6x 2 )=1/3.
Remaining work = (1 – 1/3)= 2/3
Now 3 men’s 1 day’s work =1/6
1 man’s 1 day’s work = 1/18
6 men’s 1 day’s work = (6 x 1/18=1/3
Now, 1/3 work is done by them in 1 day.
2/3 work is done by them in (3 x2/3)= 2 days.

5.(B) Part filled in 7 min = 7[ 1/36 + 1/45] = 7/20
Remaining part = [ 1- 7/20] = 13/20
Net part filled in 1 min. When A,B and C are opened
= [ 1/36 + 1/45 + 1/30 ] = 1/60
Now, 1/60 part is filled in 1 min.
13/20 part is filled in [60×13/20] = 39 min
Total time taken to fill the tank = (39 + 7) min. = 46 min.

6. (C); CP of 140 shirts and 250 trousers
= Rs (140 * 450 + 250 * 550)
= Rs. (63000 + 137500) = Rs 200500
SP for 40% profit = Rs (140/100  ×200500)=280700
Average selling price = Rs (280700/(140+250)  )=Rs.720

7. (A): Let the initial number of students in Arts and Commerce faculties be 4x and 5x respectively.
According to the question,
44x = 40x + 520
= x = 520/4 = 130
Number of students in Arts faculty = 4 * 130 = 520

8. (B) Time = 4  half years
Rate = R% per half year
A = P (1+R/100)^T
14641 = 10000 (1+R/100)^4
(1+R/100)^4 = 14641/10000= (11/10)^4
1+R/100=11/10  ? R/100=1/10
R =10%
Rate % per annum  = 20%

9. (D); Area of rectangle = Area of circle
= 22/7 * 21 * 21 = 1386 sq.cm
Let  the length and breadth of rectangle be 14x and 11x cm respectively. Then,
14x * 11x = 1386
x^2=1386/(14 ×11)=9
x = v9=3
Perimeter of rectangle = 2(14x + 11x)
= 50x = 50 * 3 = 150cm.

10.(C); Total cost of TV = Rs (12500 = 300 + 800) = Rs 13600
For a profit of 15%
Selling price = Rs. (115/100  ×13600)=Rs.15640

11. (B); required time = LCM of 24, 36 and 48 second = 144 sec. = 2 min 24 sec.

12. (A); Relative speed = (60 + 48) kmph = 108 kmph
= (108 ×5/18) m/sec = 30m/sec
Total distance = (240 + 270) metre = 510 metre
Time taken in crossing = (510/30) = 17 seconds

13. (D); Ratio of equivalent capitals of Sarita and Neeta for 1 month = 50000 * 12 : 80000 * 6
Sarita’s share = Rs (5/9  ×18000) = Rs. 10000

14. (E) A’s 1 day’s work = 1/6
B’s 1 day’s work = 1/12
(A +B)’s 1 day’s work = 1/6 + 1/12 = 2 + 1/12  = 1/4
A and B together will make 100 baskets in 4 days.

15. (C); Samir’s age = x years
His father’s age = 4x years
Reema’s age = 3/2x years

Required ratio = x : 3x/2 : 4x = 2: 3 : 8

Direction (6-9): Read the following proposition and statements, thereupon carefully answer the questions which follow.
The provisional Census 2011 figures suggest that two contrasting demographic “nations” are emerging in the country with all four south Indian States – Andhra Pradesh, Karnataka, Kerala and Tamil Nadu — already having achieved the replacement level fertility of 2.1 children per women required to initiate the process of population stabilisation, while the four large north Indian States — Bihar, Madhya Pradesh, Rajasthan and Uttar Pradesh — have still a long way to go before they achieve the required level.
