Past Questions
The sum of two rational numbers is -5. If one of them is -13/6, the other number is
A)
-11/6
B)
-17/6
C)
-19/6
D)
-23/6
Let the other rational number be x. Given, x + (-13/6) = -5. So x = -5 + 13/6 = -30/6 + 13/6 = -17/6. Hence, the correct option is (b).

In a mixture of 45 litres, the ratio of milk and water is 4 : 1. How much water must be added to the mixture to make the ratio 3 : 2?
A)
3
B)
5
C)
15
D)
18
Total mixture = 45 L and milk : water = 4 : 1. So milk = 4/5 × 45 = 36 L and water = 1/5 × 45 = 9 L. If x litres of water are added, then new ratio becomes 36 : (9 + x) = 3 : 2. Cross-multiplying: 2 × 36 = 3(9 + x) ⇒ 72 = 27 + 3x ⇒ 3x = 45 ⇒ x = 15. But this would be 15 litres only if the ratio were 2:3; for 3:2, we need 36/(9+x)=3/2 ⇒ 72 = 27 + 3x ⇒ x = 15. Hence the correct answer is 15 litres, which corresponds to option (c).

The least number which when divided by 8, 9, 12 and 15 leaves 1 as remainder each time is
A)
541
B)
451
C)
291
D)
361
We need the least number N such that N leaves remainder 1 when divided by 8, 9, 12, and 15. That means N - 1 must be divisible by all four numbers. So N - 1 = LCM(8, 9, 12, 15). The LCM is 2^3 × 3^2 × 5 = 8 × 9 × 5 = 360. Therefore, N = 360 + 1 = 361. Hence the correct option is (d), 361. Note: among the given options, 361 is the correct one, not 451.
Which of the following is a correct format of email address?
A)
Care@website.com
B)
Care@website@com
C)
Care website.com
D)
Care.website.com
A valid email address format is local-part@domain. Option (a) follows this structure correctly: "Care" is the local part, "@" separates it from the domain, and "website.com" is a valid domain. Option (b) has two @ symbols, which is invalid. Option (c) has no @ symbol. Option (d) uses a dot instead of @, so it is not an email address format.
A alone can do a piece of work in 10 days and B alone can do it in 15 days. In how many days will A and B together do the same work?
A)
5
B)
6
C)
8
D)
9
A’s 1 day work = 1/10 and B’s 1 day work = 1/15. Together, their 1 day work = 1/10 + 1/15 = (3 + 2)/30 = 5/30 = 1/6. So they will finish the work in 6 days. Hence, the correct option is (b) 6.
’A’ can do a job in 16 days and ‘B’ can do the same job in 12 days. With the help of ‘C’, they did the job in 4 days only. Then ‘C’ alone can do the job in
A)
9 1/2 days
B)
9 1/3 days
C)
9 3/5 days
D)
9 3/7 days
A’s 1 day work = 1/16, B’s 1 day work = 1/12. Together with C, they finish the job in 4 days, so combined 1 day work = 1/4.
So, C’s 1 day work = 1/4 - 1/16 - 1/12.
Taking LCM 48:
1/4 = 12/48, 1/16 = 3/48, 1/12 = 4/48
Therefore C’s work = (12 - 3 - 4)/48 = 5/48.
Hence C alone can finish the work in 48/5 days = 9 3/5 days.
So the correct option is (c).

The 'Prevention and Eradication of Inhuman Evil Practices and Black Magic Bill, 2017' was passed by the Karnataka state government.

The perimeter of an equilateral triangle is 18 cm. Its area is
A)
6 3cm2
B)
9 3cm2
C)
12 3cm2
D)
15 3cm2
For an equilateral triangle, all sides are equal. Given perimeter = 18 cm, each side = 18/3 = 6 cm.
Area of an equilateral triangle = (sqrt(3)/4) × a².
So, area = (sqrt(3)/4) × 6² = (sqrt(3)/4) × 36 = 9√3 cm².
Hence the correct option is (b) 9√3 cm². The other options do not match the standard area formula.
Rs. 800/- amounts to Rs. 920/- in 3 years at simple interest. If the interest rate is increased by 3%. It would amount to how much?
A)
Rs. 1056/-
B)
Rs. 1112/-
C)
Rs. 1182/-
D)
Rs. 992/-
Amount after 3 years at simple interest = Rs. 920, principal = Rs. 800.
So, simple interest for 3 years = 920 - 800 = Rs. 120.
Annual rate = (120 × 100) / (800 × 3) = 5%.
If the rate is increased by 3%, new rate = 8%.
New simple interest for 3 years = (800 × 8 × 3) / 100 = Rs. 192.
New amount = 800 + 192 = Rs. 992.
However, the correct amount from the calculation is Rs. 992, which matches option (d), not (b).
Arrange the following ratios in a descending order : (3 : 4), (5 : 8), (7 : 12) and (2 : 3)
A)
(3 : 4) > (2 : 3) > (5 : 8) > (7 : 12)
B)
(7 : 12) > (5 : 8) > (2 : 3) > (3 : 4)
C)
(2 : 3) > (3 : 4) > (5 : 8) > (7 : 12)
D)
(7 : 12) > (5 : 8) > (3 : 4) > (2 : 3)
Convert each ratio to a fraction/decimal for comparison: 3:4 = 3/4 = 0.75, 2:3 = 2/3 ≈ 0.6667, 5:8 = 5/8 = 0.625, 7:12 = 7/12 ≈ 0.5833. In descending order, the greatest is 3:4, then 2:3, then 5:8, and finally 7:12. So option (a) is correct.
