What will be the equation of a line with slope 3 and passing through the point (2, 1)?
Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 5 - Question 6

Let the equation of the straight line be y = mx + c [where m = slope]
Here slope = 3,
∴ y = 3x + c
The line passes through the point (2, 1),
∴ 1 = 3 × 2 + c
⇒ c = -5
∴ Equation of the straight line,
⇒ y = 3x - 5

The upper part of a tree is broken by the wind makes an angle of 60° with the ground and the distance from the root to the point where the top of the tree touches the ground is 15 m. What was the height of the tree?
Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 5 - Question 7

 
Let the tree is broken at point D,
⇒ AD = BD = x(let)
In ΔBDC,
⇒ tan60° = DC/BC = DC/15
⇒ √3 = DC/15
⇒ DC = 15√3 cm
Also, sin60° = DC/BD
⇒ √3/2 = 15√3/BD
⇒ BD = 30 cm
∴ Height of the tree = 30 + 15√3 = 15(2 + √3) cm

In the given figure, O is the centre of the circle. It is also known that OA = OB and BM = 4 cm. What is the length of QR?
Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 5 - Question 9

∵ OA is the perpendicular bisector of chord LM.
∴ BM = BL = 4 cm
⇒ LM = BL + BM = 8 cm
It is given OA = OB. i.e. chords PQ and LM are equidistant from the centre.
∴ The length of the chords will be equal.
∴ PQ = LM = 8 cm
In ΔPQR, 2 angles measure 60°, so the triangle is equilateral.
∴ PQ = QR = PR
∴ Length of QR = 8 cm

The average of 5 numbers is 25, then find new average if 1, 2, 3, 4, and 5 respectively subtracted from numbers?
Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 5 - Question 10

Let 5 numbers be v, w, x, y, z.
We are given that,
Average = (v + w + x + y + z)/5 = 25
Now, subtracting 1, 2, 3, 4, 5 respectively,
New Average = ((v - 1) + (w - 2) + (x - 3) + (y - 4) + (z - 5))/5
∴ New Average = (v + w + x + y + z)/5 - 15/5 = 25 - 3 = 22

Expenditure done on department D = 525000
Expenditure done on department F = 500000
⇒ Total expenditure done on department D and F = 1025000

Vishnu travelled equal distance at speeds of 10 km/hr, 30 km/hr, and 8 km/hr, and took a total of 15.5 minutes to complete. Find the total distance he travelled, in km.
Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 5 - Question 13

Let he travelled x km at each speed.Time taken to cover x km at 10 kmph = x/10 hr

Time taken to cover x km at 30 kmph = x/30 hr

Time taken to cover x km at 8 kmph = x/8 hr

Total time taken = 15.5 minutes = 31/120 hr

⇒ 31x = 31
∴ x = 1
∴ Total distance covered in km = 1 + 1 + 1 = 3 km

Solving the expressions,
⇒ (17/3 – 5/3) = 12/3 = 4
⇒ (22/3 – 11/3) = 11/3
⇒ (13/5 – 2/5) = 11/5

A part of the sentence is underlined and might have an error in it. Four alternatives are given for the underlined part which might improve the error if there is any, if not then click the button corresponding to “No improvement”.

Q. Samantha planned on loosening the weight that she gained over the winter, when she stayed in.
Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 5 - Question 17

‘Loosening’ should be replaced with ‘losing’ to make the sentence meaningful. Loosening is the present participle of the verb loosen, which means to let go of or to unfasten. Losing means to cause something to cease to be in one’s possession. Gaining means to get something into one’s possession. Letting go means to make something that one has to go away. Any of the other options apart from ‘losing’ does not make sense in the sentence. 
Hence the correct answer is option 1.

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 5 - Question 18

The error lies in part 1 of the sentence as the word ‘altitude’ which means 'height' is incorrect and must be replaced by the word ‘aptitude’ which means ‘ability’.

Option 1 is the correct answer.
