2. Evaluate:
cos 20° cos 40° cos 80°
A. 1/2
B. 1/4
C. 1/8
D. 1/32
Solutions
Formula:
cos3A = 4cos3A – 3cosA
cos(A + B) . cos(A – B) = cos2A – sin2B
Calculation:
⇒ ? = cos 20° cos 40° cos 80°
⇒ ? = cos 20° [cos(60° – 20°) cos(60° + 20°)]
⇒ ? = cos 20° [cos2 60° – sin2 20°]
⇒ ? = cos 20° [1/4 – (1 – cos2 20°)]
⇒ ? = 1/4 × cos20° – cos20° + cos320°
⇒ ? = cos320° – 3/4 × cos20°
⇒ ? = 1/4(4cos320° – 3cos20°)
⇒ ? = 1/4 × cos (3 × 20°)
⇒ ? = 1/4 × 1/2
⇒ ? = 1/8
∴ cos 20° cos 40° cos 80° = 1/8

6. If x3 + y3 = 35, x + y = 5, find the value of:
x4 + y4
A. 97
B. 79
C. 98
D. 87
Solutions
Given:
x3 + y3 = 35 and x + y = 5
Formula:
x3 + y3 = (x + y)3 – 3xy(x + y)
x2 + y2 = (x + y)2 – 2xy
Calculation:
Solving,
⇒ 35 = 53 – 3xy(5)
⇒ xy = 6
Then,
⇒ (x2 + y2) = 52 – 2 × 6 = 13
Then,
⇒ ? = x4 + y4
⇒ ? = (x2)2 + (y2)2

⇒ ? = 132 – 2(6)2
⇒ ? = 97
∴ x4 + y4 = 97
7. A sum of Rs. 5,000 was lent partly at 5% simple interest per annum and partly at 10% simple interest per annum. Total interest received after 5 years was Rs. 1,750. Find the amount of money that was lent out at 10% simple interet per annum.
A. Rs. 2,500
B. Rs. 2,000
C. Rs. 3,000
D. Rs. 3,500
Solutions
Given:
Total interest received after 5 years = Rs.1750
Formula:
Let P = Principal, R = rate of interest and N = time period
Simple interest = PNR/100
Calculation:
Let amount lent out at 10% simple interest be Rs.a.
Amount lent out at 5% simple interest = Rs(5000 – a)
⇒ 1750 = (a × 10 × 5)/100 + [(5000 – a) × 5 × 5/100]
⇒ 1750 × 100/5 = 10a + 25000 – 5a
⇒ 5a = 10000
⇒ a = 2000
∴ Amount lent out at 10% simple interest is Rs.2000.

11. The following bar graph shows the number of web series released by a subscription service mobile application in various years from 2014-2018 and the line graph shows the number of web series with a rating of less than 5 stars. Find the approximate total percentage of web series with a rating 5 star and above from 2014 to 2018.
A. 74
B. 71
C. 72
D. 75
Solutions
Calculation:
From graph,
Total number of web series from 2014 – 2018 = 30 + 35 + 35 + 42 + 48 = 190
Total number of web series with IMBD rating < 5 from 2014 – 2018 = 6 + 9 + 11 + 12 + 12 = 50
Total number of web series with IMBD rating 5 star and above from 2014 – 2018 = 190 – 50 = 140
∴ Required percentage = 140/190 × 100 = 73.68% ≈ 74%

A. 1200
B. 1400
C. 1600
D. 1240
Solutions
Given:
Range = 100 – 200
Formula:
a = first term, d = common difference and n = number of terms
⇒ Sn = n/2 × [2a + (n – 1)d]
⇒ Tn = a + (n – 1)d
Calculation:
Smaller term between 100 – 200 divisible by 12 = a = 108
⇒ d = 12
Larger term between 100 – 200 divisible by 12 = Tn = 192
⇒ 192 = 108 + (n – 1)12
⇒ n = 8
There are 8 terms between 100 to 200 which are divisible by 12.
Sum of such 8 terms = S8 = 8/2 × [2 × 108 + (8 – 1) × 12] = 1200
∴ The Sum of numbers between 100 to 200 which are divisible by 12 is 1200.
Hint
Sum of terms = Sn = (a + Tn) × n/2
Here,
a = 108 and Tn = 192, n = 8
Sn = (108 + 192) × 8/2 = 1200

A. p$q#r
B. p#q$r
C. p*q*r
D. p*q#r
Solutions
Given:
‘a*b’ means ‘a is the brother of b’
‘a#b’ means ‘a is the father of b’
‘a$b’ means ‘a is the wife of b’
| a is | |||
| Symbol | * | # | $ |
| Meaning | brother | father | wife |
| to b | |||
By using the symbols in the table given below, we can draw the following family tree:
1. p$q#r → p is wife of q, q is father of r
r is child of p.
2. p#q$r → p is father of q, q is wife of r
r is son-in-law of p.
3. p*q*r → p is brother of q, q is brother of r
r is either brother or sister of p.
4. p*q#r → p is brother of q, q is father of r
r is either niece or nephew of p.
Clearly, r is child of p, is possible from option 1 only.
Hence, ‘p$q#r’ is the correct answer.
33. If ‘@’ indicates either ‘+’ or ‘×’; what will be the minimum value of ‘1@2@3@4@5’?
(Note: We have a choice to replace each of the four @ signs in the expression by either ‘+’ or ‘×’ operation)
A. 12
B. 13
C. 14
D. 15
Solutions
1 × 2 = 2 and 1 + 2 = 3
Here minimum value obtained is 2 when we replace @ by × sign.
Again, we know that if we add the numbers, the value obtained will be minimum, and if we multiply the numbers, the value obtained will be maximum.
So, replacing first @ by × and remaining @ by +, we get:
1 × 2 + 3 + 4 + 5
= 2 + 3 + 4 + 5
= 14
Therefore, the minimum value of ‘1@2@3@4@5’ is 14.
Hence, ‘14’ is the correct answer.

A. 44.5
B. 44
C. 43.5
D. 43
Solutions
Given:
Mean of 150 items = 45
Formula:
Average = (Sum of elements)/(Number of terms)
Calculation:
Sum of 150 items = 45 × 150 = 6750

A. 12%
B. 9%
C. 10%
D. 8%
Solutions
Given:
Amount in 2 years = Rs.12100
Amount in 3 years = Rs.13310
Formula:
Let P = Principal, R = Rate of interest and N = time
Amount = P(1 + R/100)n
Calculation:
⇒ 12100 = P(1 + R/100)2 —-(1)
⇒ 13310 = P(1 + R/100)3 —-(2)
Dividing equation (2) by (1),
⇒ 1.1 = (1 + R/100)
⇒ 0.1 = R/100
⇒ R = 10
∴ Rate of interest is 10% per annum.

% candidates passed in only Mathematics = 35 – 20 = 15%
% candidates passed in at least one subject = 35 + 15 + 20 = 70%
% candidates failed in both subject = 100 – 70 = 30%
Let number of candidates took the exam be N.
⇒ 30/100 × N = 1200
⇒ N = 4000
∴ There are 4000 candidates who took the exam.

70. A, B and C can complete a job in 40 days, 60 days and 80 days respectively. All the three worked together but A left 11 days and B left 8 days before the completion of work. In how many days, the entire work will be completed?
A. 24 days
B. 26 days
C. 30 days
D. 28 days
Solutions
Given:
A’s 1 day’s work = 1/40
B’s 1 day’s work = 1/60
C’s 1 day’s work = 1/80
Calculation:
Let number of days in which work will be complete be n.
A worked for = (n – 11) days
⇒ A’s (n – 11) days work = (n – 11)/40
B worked for = (n – 8) days
⇒ B’s (n – 8) days work = (n – 8)/60
Then,
⇒ (n – 11)/40 + (n – 8)/60 + n/80 = 1
⇒ 6n – 66 + 4n – 32 + 3n = 240
⇒ n = 26
∴ In 26 days work will be completed.

D. 1018
Solutions
Given:
⇒ 2x + 5y = 12
⇒ xy = 2
Formula:
⇒ (a3 + b3) = (a + b)(a2 – ab + b2)
⇒ (a + b)2 = a2 + 2ab + b2
Calculation:
⇒ (2x + 5y)2 = (2x)2 + 2 × 2x × 5y + (5y)2
⇒ 144 = 4x + 25y + 20 × 2
⇒ 4x2 + 25y2 = 104
Then,
⇒ (2x)3 + (5y)3 = (2x + 5y)(4x2 – 10xy + 25y2)
⇒ 8x3 + 125y3 = 12 × (104 – 20)
∴ 8x3 + 125y3 = 1008
