The answer is, 428.4
9). Answer: e)
Explanation:
The pattern is,
(657-1)/1 = 656, (656 – 2)/2 = 327, (327-3)/3 = 108, (108 – 4)/4 = 26
The answer is, 26

11). Answer: b)
Explanation:
Mani’s monthly salary = Rs. 45000
(65/100)*Mani’s monthly salary = Rajesh monthly salary
Rajesh monthly salary = (65/100)*45000 = Rs. 29250
Rajesh’s annual salary
= > 29250*12
= > Rs. 351000
12). Answer: a)
Explanation:
Speed of train = 320/3 = 80 km/hr
Speed of car = 80 × (5/8) = 50 km/hr
Required distance = 50 × 5 = 250 km
13). Answer: d)
Explanation:
Bill paid by B = Rs. 180
Bill paid by A= 180*(160/100) = Rs. 288
(3/5) of C = 288
C = 280*(5/3)
C = Rs. 480
Total bill paid by them = 288 + 180 + 480 = Rs. 948
Average expenses = 948/3 = Rs. 316
14). Answer: c)
Explanation:
The difference between the simple interest and compound interest for 3 years is,
Diff = [sum*r2 * (r + 300)]/(100)3
492.8 = [Sum*64*308]/(100*100*100)
Sum = (492.8*100*100*100)/(64*308)
Sum = Rs. 25000
15). Answer: a)
Explanation:
The share of A, B and C
= > [6x*5 + (6x + 4000)*7]: [7x*12]: [3x*5 + (3x + 6000)*7]
= 374: 420: 201
= > [30x + 42x + 28000]: [84x]: [15x + 21x + 42000] = 374: 420: 201
= > [72x + 28000] : [84x] : [36x + 42000] = 374 : 420 : 201
According to the question,
(72x + 28000) /84x = (374/420)
360x + 140000 = 374x
14x = 140000
X = 10000
The initial investment of B = 7x = Rs. 70000
Direction (16-20) :
16). Answer: c)

Required difference = 8400 – 4800 = 3600
17). Answer: a)
Explanation:
The total number of television viewers of Polimer TV
= > 75000*(15/100) = 11250
The total number of female television viewers of Colors TV

Required ratio = 11250: 10000 = 9: 8
18). Answer: d)
Explanation:
Total number of television viewers of Times Now
= > 75000*(14/100) = 10500
Total number of male television viewers of ZEE TV
= > 75000*(18/100)*(4/9) = 6000
Required % = (10500/6000)*100 = 175 %
19). Answer: b)
Explanation:
The total number of male television viewers of Polimer TV, Star Vijay and Colors TV together
= > 75000*(15/100)*(5/9) + 75000*(21/100)*(7/15) + 75000*(20/100)*(1/3)
= > 6250 + 7350 + 5000 = 18600
Required average = 18600/3 = 6200
20). Answer: c)
Explanation:
Total number of female television viewers of Star news
= > 75000*(12/100)*(7/15) = 4200
Total number of male television viewers of ZEE TV
= > 75000*(18/100)*(4/9) = 6000
Required % = [(6000 – 4200)/6000]*100 = 30 % less
