Directions: In the question given below a statement is followed by two arguments numbered I and II. You have to decide which of the given arguments is a ‘strong’ argument and which is the ‘weak’ argument.
Statement: Should doctors/authorities who do not treat any critical patient because of insufficient money be put on trial.
Argument I: No. Since nothing is for free.
Argument II: Yes. Patient's life should be given priority over the money by doctor.
It is true that nothing is for free but a life is worth more than any amount of money and money comes and goes but a person once dead cannot be brought back to life. So doctors/authorities who do not treat critical patients just because of insufficient money should be put on trial. Hence only argument II is strong and option 2 is correct.

A is three times as efficient as B and takes 60 days less than B for doing a job. The time in which they can do it together is?
Let the number of days in which B does a job be x.
Given, A is three times as efficient as B and takes 60 days less than B for doing a job.
Number of days in which A finishes the job = x – 60
In 1 day, B finishes 1/x of the work.
∴ A finishes 3/x of the work in 1 day.
Thus, A will finish the work in x/3 days.
⇒ x/3 = x – 60
⇒ 2x/3 = 60
⇒ x = 90 days
Thus, B finishes the work in 90 days, while A finishes it in 30 days.
Working together in 1 day, they finish part of work = 1/90 + 1/30
Thus they will finish the work in number of days = 90/4 = 22.5 days

⇒ Water in the first mixture = x/(2x + x) = 1/3
⇒ Milk in the Second mixture = x/(x + x) = 1/2
⇒ Water in the second mixture = x/(x + x) = 1/2
⇒ Ratio of Milk and water in new mixture = (2/3 + 1/2)/(1/3 + 1/2)
⇒ Ratio of Milk and water in new mixture = {(2 × 2 + 1 × 3)/6}/{(2 × 1 + 3 × 1)/6}
⇒ Ratio of Milk and water in new mixture = (7)/(5)
∴ Ratio of Milk and water in new mixture = 7 : 5
A man had Rs. 8000. He lent a part of it at 8% at SI and the remaining at 6% SI. His total annual income was Rs. 600. Find the sum lent at 8% rate.
SI = (P × r × t)/100
Where, P is principal, r is rate% and t is time.
Given, man had Rs. 8000. He lent a part of it at 8% at SI and the remaining at 6% SI. His total annual income was Rs. 600.
Let the sum lent at 8% be ‘a’.
Sum lent at 6% = 8000 – a
SI at 8% for 1 year = (a × 8 × 1)/100 = 0.08a
SI at 6% for 1 year = ((8000 – a) × 6 × 1) /100 = 480 – 0.06a
Given, total income = Rs. 600
⇒ 0.08a + 480 – 0.06a = 600
⇒ 0.02a = 120
⇒ a = Rs. 6000

mc (T_{f} – 30) = mc (50 – T_{f})
T_{f} = (30 + 50)/2 = 40°C
If the radius of a circle is increased by 25%, its area increases by:
Let the radius of the circle be x cm.
So, area = πx^{2} cm^{2}.
The radius of a circle is increased by 25%.
So, the increased radius = x × (125/100) = 5x/4 cm
Now, area = π × (5x/4)^{2} cm^{2} = 25πx^{2}/16 cm^{2}
So, increase in area = (25πx^{2}/16) – πx^{2} = 9πx^{2}/16 cm^{2}
∴ The required percentage change = [{(9πx^{2}/16)/πx^{2}} × 100% = 56.25%

In what ratio is the segment joining the points (2, 5) and (6, 10) divided by the yaxis?
Let the segment divides y axis in K : 1 ratio.
If ratio m ∶ n is the intersection then formula for coordinates dividing is given by,
(mx_{2} + nx_{1})/(m + n), (my_{2} + ny_{2})/(m + n)
As, the intersection point is on y axis, the value of x coordinate = 0
So,
(6k + 2)/(k + 1) = 0
⇒ 6k + 2 = 0
⇒ k = 1/3
∴ The required ratio = k : 1 = (1/3) : 1 = 1 : 3.

The length of a rectangle is increased by 20% and breadth decreased by 20%. The area of the new rectangle is?
Let,
Original length of the rectangle = L
Original breadth of rectangle = B
∴ Original area = Length × Breadth = L × B
After increasing 20% Length becomes = L + 0.20L = 1.20L
After decreasing 20% Breadth becomes = L – 0.20L = 0.80L
∴ New area becomes = Length × Breadth = 1.20L × 0.80B = 0.96 × L × B

If difference between the squares of two consecutive numbers is 45. Find the largest number.
Let the number be x,
Then, consecutive number will be (x + 1)
Given that, (x + 1)^{2} – (x)^{2} = 45
Using (a + b)^{2} = a^{2} + 2ab + b^{2}
⇒ x^{2 }+ 1 + 2x – x^{2} = 45
⇒ 2x = 45  1 = 44
⇒ x = 22
∴ The largest number is 23.
