Pipes P and Q are inlet pipes while pipe R is an outlet pipe of a tank. Pipe P supplies water at 30 litres/hour. Pipe Q can fill the tank in 6 hours while pipe R can empty it in 24 hours. The empty tank gets filled in 2 hours when all the three pipes are opened simultaneously. What is the capacity of the tank.

Correct

Answer – 3) 80 liters
Explanation
The fraction of the tank filled by Q in 2 hours = 1/3
R emptied in 2 hours 2/24 = 1/12
The fraction of tank filled by Q and R in 2 hours
= (1/3) – (1/12 )= 1/4
So (3/4) filled by P in 2 hours.
Water supplied by P in 2 hours = 2 x 30 = 60 liters
Capacity = 60 x 4/3 = 80 liters

Incorrect

Answer – 3) 80 liters
Explanation
The fraction of the tank filled by Q in 2 hours = 1/3
R emptied in 2 hours 2/24 = 1/12
The fraction of tank filled by Q and R in 2 hours
= (1/3) – (1/12 )= 1/4
So (3/4) filled by P in 2 hours.
Water supplied by P in 2 hours = 2 x 30 = 60 liters
Capacity = 60 x 4/3 = 80 liters

Let speed of current be s km/hr
Speed of the boat in still water = 5s km/hr
40/s+5s + 40/5s-s =10
5 = 3s
S = 5/3 km/hr

Answer – 2) 1400
Explanation
Let each instalment be Rupee x.
After four years, the first instalment, (paid at the end of first year) will amount x +x(3) (10/100) i.e. x(1.3)
Similar for 2,3 and 4 year will amount x(1.2),x(1.1) and x respectively.
Total amount paid = x(1.3) + x(1.2) + x(1.1) +x =x(4.6)
Given sum to be repaid = 6440
X(4.6) = 6440
X= 1400

Incorrect

Answer – 2) 1400
Explanation
Let each instalment be Rupee x.
After four years, the first instalment, (paid at the end of first year) will amount x +x(3) (10/100) i.e. x(1.3)
Similar for 2,3 and 4 year will amount x(1.2),x(1.1) and x respectively.
Total amount paid = x(1.3) + x(1.2) + x(1.1) +x =x(4.6)

Rohan went to the market to purchase three pens. The cost of the first pen was more than that of the second by 25% which was more than that of the third by 20%. If the average cost of the first two pens was Rupee 15 more than that of the last two pens, find the cost of the costliest pen

Correct

Answer – 4) 90
Explanation
Let cost of second be x , the cost of the first pen = x + 25x/100 = 5x/4
Cost of third be y
x= y + 20y/100 = 6y/5
y=5x/6
5/4x+x / 2 = x+5/6x /2 + 15 = x+5/6x+30 / 2
(1/4 – 1/6)x = 6
X=12 x 6 =72
The costliest = 5/4 x 72 = 90

Incorrect

Answer – 4) 90
Explanation
Let cost of second be x , the cost of the first pen = x + 25x/100 = 5x/4
Cost of third be y
x= y + 20y/100 = 6y/5
y=5x/6
5/4x+x / 2 = x+5/6x /2 + 15 = x+5/6x+30 / 2
(1/4 – 1/6)x = 6
X=12 x 6 =72
The costliest = 5/4 x 72 = 90
