A)
-(x-5)/(x+7)
B)
-(x+5)/(x+7)
C)
x-7/(x+5)
D)
x+5/(x=7)
The additive inverse of a number/expression is what must be added to it to get 0. For any expression A, its additive inverse is -A. Here A = (x-5)/(x+7), so the additive inverse is -(x-5)/(x+7). Option (a) is correct. The other options do not represent the negative of the given fraction.
The marks obtained by 20 students in a Mathematics test (out of 100) are given below: 99, 36, 91, 82, 100, 96, 100, 65, 76, 82, 90, 46, 72, 64, 66, 68, 49, 48, 79, 55. The range of the data is:
A)
36
B)
64
C)
54
D)
100
The range of a data set is the difference between the highest and lowest values. Here, the highest mark is 100 and the lowest mark is 36. So, range = 100 - 36 = 64. Hence, the correct answer is (b) 64.
A train running at a speed of 90 km/h passes a pole on the platform in 12 seconds.The length of the train, in metres is
A)
200
B)
300
C)
325
D)
250
Speed = 90 km/h = 90 × (1000/3600) = 25 m/s. When a train passes a pole, it covers its own length in the given time. So, length = speed × time = 25 × 12 = 300 m. Therefore, the correct length should be 300 m, which is option (b). However, since the options include 300 and the calculation is definitive, the correct option is (b).
How much fine will be imposed on the first time offender according to the bill passed for e-cigarettes ban?
A)
Rs. 1 lakh
B)
Rs. 2 lakhs
C)
Rs. 3 lakhs
D)

The bill for banning e-cigarettes prescribed a fine of Rs. 1 lakh for a first-time offender. For repeat violations, the penalty becomes much higher, which helps distinguish the first-offence amount from later offences. Hence, option (a) is correct.
The area of an equilateral triangle whose sides are 4 cm is
A)
8Ö3 cm2
B)
4Ö3 cm2
C)
24Ö3 cm2
D)
16Ö3 cm2
For an equilateral triangle, area = (√3/4) × a². Here a = 4 cm, so area = (√3/4) × 16 = 4√3 cm². Hence the correct option is (b). Option (a) is too large, and (c) and (d) are far larger than the correct value.
In a group of 70 people, 50 people speak French, 20 speak Spanish and 10 speak both Spanish and French. How many speak at least one of these languages?
A)
10
B)
20
C)
50
D)
60
Use the formula for union of two sets:
Number speaking at least one language = French + Spanish - Both
= 50 + 20 - 10
= 60.
So, 60 people speak at least one of these languages. Option (d) is correct.

A)
12 and 15
B)
13 and 14
C)
11and 16
D)
8 and 19
Let the numbers be x and y. We know x + y = 27 and xy = 182. We check the options: 13 + 14 = 27 and 13 × 14 = 182, so they satisfy both conditions. The other pairs do not give both the required sum and product.
Which is called ‘Land of rice and teak’?
A)

Zawma crosses a path 600 m long in 5 minutes. His speed in km/h is
A)
7.2
B)
12
C)
8.2
D)
10
Speed = distance/time. Here, distance = 600 m = 0.6 km and time = 5 minutes = 5/60 hour = 1/12 hour. So speed = 0.6 ÷ (1/12) = 0.6 × 12 = 7.2 km/h. Hence, the correct option is (a).
