Direction (6-10 :
6). Answer: c)
Explanation:
(62)4 ÷ (9720/45)3 × (96 × 81)2 = (6)x + 8
68 ÷ (216)3 × (7776)2 = 6x + 8
68 ÷ (63)3 × (65)2 = 6x + 8
68 ÷ (69) × (610) = 6x + 8
68 -9 + 10 = 6x+ 8
69 = 6x + 8
X + 8 = 9
X = 1
Answer: a)
7). Explanation:
(58/100)*1650 + (5/21)*20370 – (32/100)*1500 = x
X = 957 + 4850 – 480
X = 5327
8). Answer: d)
Explanation:
13 5/8 + 11 ¾ – 9 ½ – 10 1/4 + 5 ¼ = x
(13 + 11 – 9 – 10 + 5) (5/8 + ¾ – ½ – ¼ + 1/4) = x
X = 10 [(5 + 6 – 4)/8]
X = 10 (7/8)
9). Answer: b)
Explanation:
∛(373248) % of 750 – √26244 ÷ 27 = (3/7) * (4/3) * 2016 – x
72 % of 750 – (162/27) = (3/7) * (4/3) * 2016 – x
(72/100)*750 – 6 = 1152 – x
540 – 6 = 1152 – x
X = 1152 – 534
X = 618
10). Answer: a)
Explanation:
(52*52*22)/13 + 729 = 4x – (65/100)*3900
4576 + 729 + 2535 = 4x
4x = 7840
X = 1960
11). Answer: c)
Explanation:
The ratio between the present ages of P and Q = 3 : 5 (3x, 5x)
Present age of R = Present age of Q + 7 = 5x + 7
The average present age of P, Q and R = 24 years
The total present age of P, Q and R = 24*3 = 72 years
According to the question,
3x + 5x + 5x + 7 = 72
13x = 65
X = 5
Present age of R = 5x + 7 = 25 + 7 = 32 years
12). Answer: a)
Explanation:
The share of A, B and C
= > [x*12] : [2x*6 + (2x + 6000)*6] : [4x*12] = 20 : 43 : 80
= > [12x] : [12x + 12x + 36000] : [48x] = 20 : 43 : 80
= > 12x : 24x + 36000 : 48x = 20 : 43 : 80
According to the question,
= > 12x/(24x + 36000) = (20/43)
= > 120x + 180000 = 129x
= > 9x = 180000
= > x = 20000
The initial investment of C = 4x = Rs. 80000
13). Answer: d)
Explanation:
Total Quantity = 240 liters
The ratio of milk to water = 7 : 5
Milk = 140 liters, Water = 100 liters
According to the question,
140/(100 + x) = 7/8
160 = 100 + x
X= 60 liters
So, 60 liters of water should be added.
14). Answer: b)
Explanation:
A’s whole work,
(2/3)*A’s work = 16
A’s work = 16*(3/2) = 24 days
(A+ B)’s work = 8 days
B’s one day work = (1/8) – (1/24) = 1/12
B’s whole work = 12 days
(B : C)’s efficiency = 1 : 2
(B : C)’s day ratio = 2 : 1
So, 2’s = 12
1’s = 6
C’s whole work = 6 days
15). Answer: c)
Explanation:
Let the original fraction be x/y,
[X*(125/100)] / [y*(85/100)] = 35/68x/y = (35/68)*(85/125)
x/y = (7/20)
Direction (16-20) :
16). Answer: b)
Explanation:
Total profits of company P, R and T together in the year 2015
= > 75 + 85 + 80 = 240 lakhs
Total profits of company Q, R and S together in the year 2017
= > 70 + 110 + 135 = 315 lakhs
Required % = (240/315)*100 = 75 %
17). Answer: C)
Explanation:
The average profits of all the given companies together in the year 2016
= > (50 + 80 + 120 + 130 + 110)/5
= > 490/5 = 98 lakhs
18). Answer: a)
Explanation:
Total profits of all the given years together in the year 2015
= > 75 + 100 + 85 + 95 + 80 = 435 lakhs
Total profits of all the given years together in the year 2017
= > 60 + 70 + 110 + 135 + 125 = 500 lakhs
Required difference = 500 – 435 = 65 lakhs
19). Answer: c)
Explanation:
The total profits of company Q in all the given years together
= > 100 + 80 + 70 = 250 lakhs
The total profits of company R in all the given years together
= > 85 + 120 + 110 = 315 lakhs
Required ratio = 250 : 315 = 50 : 63
20). Answer: b)
Explanation:
Total profits of company P in all the given years together
= > 75 + 50 + 60 = 185 lakhs
Total profits of company S in all the given years together
= > 95 + 130 + 135 = 360 lakhs
Required % = [(360 – 185)/360]*100 = 48.6 % = 50 % less
