1. 161.52%     2. 195.5%     3. 182%         4. 190%         5. 171.42%

Answer

1. Answer : 1


Explanation :  Quantity of Guava at Shop A = 1200×10100 = 120 kg 


Quantity of Guava at Shop B = 1000×16100= 160 kg


Therefore, Required difference = 160 - 120 = 40 kg


 


2. Answer : 2


Explanation : Cost of Mango at Shop A = 30×1200×24100= Rs. 8640 


Cost of Apple = 40×1200×16100 = Rs. 7680 


Cost of Orange = 20×1200×20100 = Rs.4800 


Therefore, Required Ratio = 8640 : 6780 : 4800  = 9 : 8 : 5 


 


3. Answer : 3 


Explanation : Quantity of Mango at Shop B = 1000×24100 = 240 kg 


Quantity of Mango at Shop A =1200×24100 = 288 kg


 Therefore, Req % = 288×100240 = 120% of the quantity of Mango at Shop A


 


4. Answer : 4 


Explanation : Cost of total fruits at Shop A = Cost of Mango + Cost of Apple + Cost of Guava + Cost of orange + Cost of other fruits


 =1200×24100×30 + 1200×16100×40 + 1200×10100×18 + 1200×20100×20 + 1200×30100×15 


= Rs. 28680 


Cost of Total Fruits at Shop B


=1000×24100×30 + 1000×14100×40 + 1000×16100×18 + 1000×20100×20 + 1000×26100×15


= 7200 + 5600 + 2880 + 4000 + 3900 


= Rs. 23580


Therefore, Req.difference = 28680 - 23580 = Rs.5100


 


5. Answer : 5


Explanation: Quantity of Orange at Shop A = 1200×20100 = 240 kg 


Quantity of Apple at Shop B =1000×14100 = 140 kg


 Therefore, Req % = 240×100140 = 171.42% more than the quantity of Apple at Shop B.

Q:

If y/(x - z) = (y + x)/z = x/y then find z : y : x ?

A) 1:2:3 B) 3:2:4
C) 4:3:2 D) 2:3:4
 
Answer & Explanation Answer: B) 3:2:4

Explanation:

Given, y/(x - z) = (y + x)/z = x/y
yz = xy + x2 - yz - xz ....(1)
Also xy = yx-z x2 -xz = y2 ....(2)
Using (1) and (2), we get yz = xy - yz + y2
2yz = xy + y2
2z = x + y
Only option (B) satisfies the equation.

Q:

Train K crosses a stationary Train L in 50 seconds and a pole in 20 seconds with the same speed. The length of the Train K is 240 meters. What is the length of stationary Train L ?

A) 60 mts B) 120 mts
C) 240 mts D) 360 mts
 
Answer & Explanation Answer: D) 360 mts

Explanation:

Speed of the Train K is given by s = d/t = 240/20 = 12 m/s
Distance covered by Train K in 50 seconds = 12 x 50 = 600 mts.
But it crosses Train L in 50 seconds
Therefore, the length of the Train L is = 600 - 240 = 360 mts.

Q:

Three taps P, Q and R can fill a tank in 12 hrs, 15 hrs and 20 hrs respectively. If P is open all the time and Q and R are open for one hour each alternately, starting with Q, then the tank will be full in how many hours ?

A) 9 hrs B) 7 hrs
C) 13 hrs D) 11 hrs
 
Answer & Explanation Answer: B) 7 hrs

Explanation:

Given,

P can fill in 12 hrs

Q can fill in 15 hrs

R can fill in 20 hrs

=> Volume of tank = LCM of 12, 15, 20 = 60 lit

=> P alone can fill the tank in 60/12 = 5 hrs

=> Q alone can fill the tank in 60/15 = 4 hrs

=> R alone can fill the tank in 60/20 = 3 hrs

Tank can be filled in the way that

(P+Q) + (P+R) + (P+Q) + (P+R) + ....

=> Tank filled in 2 hrs = (5+4) + (5+3) = 9 + 8 = 17 lit

=> In 6 hrs = 17 x 6/2 = 51 lit

=> In 7th hr = 51 + (5+4) = 51 + 9 = 60 lit

=> So, total tank will be filled in 7 hrs.
