Direction (6-10) :
6). Answer: c)
Explanation:
√(21609) ÷ 7 × 15 = x – 16758 ÷ 9
(147/7)*15 = x – (16758/9)
315 + 1862 = x
X = 2177 = 2180
7). Answer: a)
Explanation:
132 + 48 % of 700 – (2/7) of 1225 = ? – 63
169 + (48/100)*700 – (2/7)*1225 + 216 = x
X = 169 + 336 – 350 + 216 = 371
X = 370
8). Answer: e)
Explanation:
34485 ÷ 11 + (5/9) of 12150 + 56 % of 9000 = x2 – 451
(34485/11) + (5/9)*12150 + (56/100)*9000 = x2 – 451
3135 + 6750 + 5040 + 451 = x2
X2 = 15376
X = 124
9). Answer: d)
Explanation:
x % of 500 – 8 % of 3000 – (3/8) of (2/3) of 72 = 23
x*(500/100) – (8/100)*3000 – (3/8)*(2/3)*72 = 23
5x – 240 – 18 = 23
5x = 23 + 240 + 18
5x = 281
X = 281/5 = 56
10). Answer: b)
Explanation:
182 – (7/4) × (36 ÷ 9) + 33 = x + 112
324 – 7 + 27 – 121 = x
X = 223
11). Answer: a)
Explanation:
A and B together can complete a work in = 15 days
(A + B)’s one day work = 1/15
A alone can complete the work in = 24 days
A’s one day work = 1/24
B’s one day work = 1/15 – 1/24 = (24 – 15)/(15*24) = 1/40
B can complete the work in 40 days
Total units = 120 (LCM of 24, 40)
A’s one day work = 5 units
B’s one day work = 3 units
Work done in 2 days = 5 + 3 = 8 units
Work done in 30 days = 8*15 = 120 units
Work will be completed in 30 days
12). Answer: c)
Explanation:
The ratio of share of P, Q and R
= > [45000*3 + 45000*(60/100)*9]: [60000*6 + 60000*(70/100)*6]: [70000*3 + 70000*(120/100)*9]
= > 378000: 612000: 966000
= > 189: 306: 483
The share of Q = Rs. 38250
306’s = 38250
1’s = 125
Total profit = 978’s = Rs. 122250
13). Answer: d)
Explanation:
A, B and C’s efficiency ratio = (1/15) : (1/12) : (1/24)
= > (8: 10: 5)/120
= > 8: 10: 5
23’s = 3450
1’s = 150
The share of A = 8*150 = Rs. 1200
14). Answer: b)
Explanation:
S.I = PNR/100
12000 = (50000*3*R)/100
R = (12000*100)/150000 = 8 %
The corresponding C.I:
50000*(8/100) = 4000
54000*(8/100) = 4320
58320*(8/100) = 4665.6
C.I = 4000 + 4320 + 4665.6 = Rs. 12985.60
15). Answer: d)
Explanation:
The cost of fencing the plot at Rs. 40 per meter is Rs. 8400
= > 7280/40 = Perimeter of Rectangle
= > 182 = 2*(8x + 5x)
= > 13x = 91
= > x = 7
The length and the breadth of rectangular plot are in the ratio of 8:5
= > Length = 8x = 56 m, Breadth = 5x = 35 m
Area of the plot = 56*35
= > 1960 Sq meter
Direction (16-20) :
16). Answer: b)
Explanation:
The total number of students passed the examination from School P in all the given years together
= > 1152 + 1348 + 1546 + 1274 + 1056 = 6376
The total number of students passed the examination from School T in all the given years together
= > 1326 + 1420 + 1278 + 1356 + 1452 = 6832
Required ratio = 6832: 6376 = 854 : 797
17). Answer: d)
Explanation:
The total number of students passed in the year 2013 from all the given Schools together
= > 1348 + 1636 + 1024 + 1338 + 1420 = 6766
The total number of students passed in the year 2015 from all the given Schools together
= > 1274 + 1885 + 1058 + 1560 + 1356 = 7133
Required difference = 7133 – 6766 = 367
18). Answer: a)
Explanation:
The total number of students passed in the year 2016 of all the given schools together
= > 1056 + 1434 + 1278 + 1340 + 1452 = 6560
Required average = 6560/5 = 1312
19). Answer: c)
Explanation:
The ratio between the total number of male and female passed from School Q in 2012 = 11 : 8
The ratio between the total number of male and female passed from School S in 2015 = 5 : 3
The total number of male passed from School Q in 2012
= > 1520*(11/19) = 880
The total number of female passed from School S in 2015
= > 1560*(3/8) = 585
Required % = (880/585)*100 = 150 %
20). Answer: b)
Explanation:
The total number of students passed from School Q in all the given years together
= > 1520 + 1636 + 1780 + 1885 + 1434 = 8255
The total number of students passed in the year 2014 from all the given schools together
= > 1546 + 1780 + 1136 + 1280 + 1278 = 7020
Required % = [(8255 – 7020)/7020]*100 = 18 % more
