Direction (6-10) :
6). Answer: a)
Explanation:
I. x2 – 12x + 36 = 0
(x – 6)(x – 6) = 0
X = 6, 6
II. 5y2 + 4y – 12 = 0
5y2 + 10y – 6y – 12 = 0
5y (y + 2) – 6 (y + 2) = 0
(5y – 6) (y + 2) = 0
Y = 6/5, – 2 = 1.2, -2
x > y
7). Answer: c)
Explanation:
I. 2x2 + 12x + 16 = 0
2x2 + 4x + 8x + 16 = 0
2x(x + 2) + 8(x + 2) = 0
(2x + 8)(x + 2) = 0
X = -4, -2
II. 3y2 -7y – 6 = 0
3y2 -9y + 2y – 6 = 0
3y(y – 3) + 2(y – 3) = 0
(3y + 2) (y – 3) = 0
Y = – 2/3, 3 = -0.667, 3
x < y
8). Answer: a)
Explanation:
7x + 2y = -13–à (1)
5x – 4y = 7–à (2)
By solving the equation (1) and (2), we get,
X = – 1, y = -3
X > y
9). Answer: e)
Explanation:
I. x2 + 2x – 15 = 0
(x + 5) (x – 3) = 0
X = -5, 3
II. y2 + y – 56 = 0
(y + 8) (y – 7) = 0
Y = -8, 7
Can’t be determined
10). Answer: c)
Explanation:
I. √25 x + √5625 = 0
5x = – 75
X = -15
II. (243)1/5 y + (1728)1/3 = 0
(35)1/5 y = – (123)1/3
3y = -12
Y = -4
X < y
11). Answer: a)
Explanation:
Let Manju’s monthly salary be x,
According to the question,
X*(65/100)*(60/100) = 15600
X = 15600*(100/65)*(100/60)
X = Rs. 40000
12). Answer: d)
Explanation:
Total age of 35 students = 35*15 = 525
Total age of (35 students + 1 teacher) = 36*16 = 576
The age of teacher = 576 – 525 = 51 years
The age of teacher’s wife = 51 – 5 = 46 years
(Or)
If both n and average increase or decrease 1, then,
The age of teacher = (35 + 16) or (36 + 15) = 51 years
The age of teacher’s wife = 51 – 5 = 46 years
13). Answer: b)
Explanation:
The share of A, B and C
= > [40000*12] : [50000*4 + 50000*(70/100)*8] : [20000*6]
= > 480000: 480000: 120000
= > 4: 4: 1
1’s = 15000
Total profit = 9’s = Rs. 135000
14). Answer: a)
Explanation:
The difference between the simple interest and Compound interest on 3 years is,
Diff = [Sum * r2 * (r + 300)]/(100)3
440.64 = [Sum * 62 * (6 + 300)]/(100)3
440.64 = [Sum * 36 * (306)]/(100)3
Sum = [440.64*100*100*100]/(36*306)
= > Rs. 40000
15). Answer: d)
Explanation:
Let passed students be x,
According to the question,
57*24 = 26*x + 7*(57 – x)
1368 = 26x + 399 – 7x
969 = 19x
X = 969/19 = 51
Total number of passed students = 51
Direction (16-20) :
16). Answer: c)
Explanation:
The total number of students participated in Football from School P and R together
= > 1500*(32/100) + 1300*(26/100)
= > 480 + 338 = 818
The total number of students participated in Tennis from School Q and S together
= > 2200*(24/100) + 1800*(26/100)
= > 528 + 468 = 996
Required ratio = 818: 996 = 409: 498
17). Answer: a)
Explanation:
The total number of students didn’t participated in any sports from School P
= > 1500*(25/100) = 375
The total number of students didn’t participated in any sports from School T
= > 2000*(33/100) = 660
Required difference = 660 – 375 = 285
18). Answer: d)
Explanation:
The total number of students participated in Kabaddi from School Q, R and S together
= > 2200*(12/100) + 1300*(18/100) + 1800*(20/100)
= > 264 + 234 + 360 = 858
Required average = 858/3 = 286
19). Answer: b)
Explanation:
Total number of students participated in Tennis from School Q
= > 2200*(24/100) = 528
Total number of students participated in Football from School S
= > 1800*(32/100) = 576
Required % = (528/576)*100 = 92 %
20). Answer: c)
Explanation:
Total number of students didn’t participated in any sports from School S
= > 1800*(22/100) = 396
Total number of students didn’t participated in any sports from School T
= > 2000*(33/100) = 660
Required % = [(660 – 396)/660]*100 = 40 % less
