Solutions:

1. (14.4/80 – 14.4/104)/(14.4/80) = 24/104 = 23.07%. Option d.

2. We have to simply answer it as a yes/no question. Now, if we look at statement I, we can easily figure out the answer to the question. So, statement I is enough in itself and so, the other two statements have to be redundant. As only option c satisfies, that is our answer. We can check for the other two statements as well if we feel like but in a speed based test, it doesn’t really matter.

Statement II: a + b > 2b or a > b is enough as if we add 7 to both the numerator and denominator, it will add more to the numerator than to the denominator and so, I and III will be redundant.

Statement III: a – 5 > b – 5 and so, a > b and so, I and II will be redundant.

You could have easily saved some time by skipping the above two steps. Option c.

3. COV is to check for all the given parameters. The fact that consistency and disparity is there in the options would strongly point towards both of them being included in the answer. Option d.

4. 3(c+w) = 4(c-w) = 1 and so, c = 7w. So, c = 7/24 km/hr and so, to cover 1 km, he takes 24/7 hours.

5. Let’s take numbers here. Total investment be Rs. 120. A put in 60, B put in 40, C put in 20 for say the duration of 1 year. A invested it for 4 months and so, 240 units worth of investment, similarly B put in 120 units of capital. At this point in time, you can check for options and mark option c.

If you check though, C put in 240 units and so, we have proven that option c is right.

6. Total combinations are 1000. Out of these, exactly 1 is correct. So, 999 are wrong. Option d.

7. f + s = 18, 10f + 3s = 110. f = 8 and s = 10. If the tickets are interchanged, we get Rs. 124 as our answer. Option d.

8. 18 hours and 20 minutes have passed. If it loses 12 minutes in 24 hours, it loses 9 minutes in 18 hours. If it loses 0.5 minutes = 30 seconds in 1 hour, it loses 10 seconds in 20 minutes. So, it loses 9 minutes and 10 seconds. So, it will show 1:35:50 pm. Option b.

9. 11th from the left is 9th from the right. Total of 19 people. Option b.

10. Statement 1: 30% profit

Statement 2: 85 g at Rs. 115. So, 100 g at 2300/17 = 135.xx

Statement 3: 700 g at Rs. 1000. So, 1000 g at 10000/7 = 1428.xx

Statement 4: 1000 g at Rs. 1300. So, 30% profit

Option a.

11. We need both the statements to answer the question. Option d.

12. Area of square = 2624.40/160 = 164 hectares. 1 hectare is 10000 sq.m. So, side of the square is √164025 = 405 m. As there are 4 sides and Rs. ¼ per m, we the answer as Rs. 405. Option d.

13. In the first case, the length of the shadow will be h√3 and in the second case, it will be h/√3. As the difference is 60, we get h = (60√3)/2 = 51.96 m. Option b.

14. 1 + 2 + 3 + … should be =< 288.

n(n+1) =< 576

n = 23 and so, it should be the 24th alphabet i.e. x. Option d.

15. Putting values should help if you are not comfortable with factorization. p = 7 violates the inequality and so, option d is out. p = 5 satisfies and so, option b is out. p = -2 violates the inequality and so, option c is out. Option a is correct.

Note that this was classified as an ambiguous question because it does not really satisfy the inequality.
