Option 2: Drought
Option 3: Below average and late monsoon
Option 4: Above average and early monsoon
Correct Answer: Below average and late monsoon
Solution : The correct option is Below-average and late monsoon.
The negative pressure anomalies in Tahiti, as part of the Southern Oscillation or La Nina pattern, can lead to below-average monsoon rainfall in various regions and cause a delay in the onset of
Question : If $x=\frac{3}{2}$, then the value of $27x^{3}-54x^{2}+36x-11$ is:
Option 1: $11\frac{3}{8}$
Option 2: $11\frac{5}{8}$
Option 3: $12\frac{3}{8}$
Option 4: $12\frac{5}{8}$
Correct Answer: $12\frac{5}{8}$
Solution : Given: $27x^{3}–54x^{2}+36x–11$ Putting the value of $x=\frac{3}{2}$ in the above equation $27×(\frac{3}{2})^{3}–54×(\frac{3}{2})^{2}+36×\frac{3}{2}–11$ = $27×(\frac{27}{8})–54×(\frac{9}{4})+36×\frac{3}{2}–11$ = $\frac{729}{8}–\frac{486}{4}+\frac{108}{2}–11$ = $\frac{729–972+432–88}{8}$ = $\frac{101}{8}$ = $12\frac{5}{8}$ Hence, the correct answer is $12\frac{5}{8}$.
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.) (72, 84, 42) (96, 108, 54)
Option 1: (92, 102, 51)
Option 2: (112, 120, 60)
Option 3: (88, 100, 50)
Option 4: (64, 86, 42)
Correct Answer: (88, 100, 50)
Solution : Given: (72, 84, 42); (96,108, 54)
Add 12 to the first number, to get the second number, and divide the second number by 2, to get the third number – ⇒ (72, 84, 42)→17 + 12 = 84; 84 ÷ 2 = 42
Question : At what rate of compound interest per annum, a sum of Rs. 20,000 becomes Rs. 23,152.50 in 1 year and 6 months compounded half-yearly?
Option 1: 10% per annum
Option 2: 5% per annum
Option 3: 12% per annum
Option 4: 8% per annum
Correct Answer: 10% per annum
Solution : Given: At what rate of compound interest per annum, a sum of Rs. 20,000 becomes Rs. 23,152.50 in 1 year and 6 months compounded half-yearly Here Principle ($P$) = Rs. 20,000 Amount ($A$) = Rs. 23,152.50 Time = 1 year 6 months =
Question : Directions: In the following figure, the square represents Pharmacists, the triangle represents Singers, the circle represents Surgeons and the rectangle represents Mothers. Which set of letters represents Surgeons who are either Mothers or Singers?
Option 1: E, D, G
Option 2: A, F, C
Option 3: A, D, C
Option 4: H, B, C
Correct Answer: A, F, C
Solution : In the diagram, the shaded part represents the overlapping region between Surgeons and Mothers as well as the overlapping region between Surgeons and Singers. Letters falling in the region of Pharmacists will also be considered in the case of overlapping as there is

Question : Directions: The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) is/are followed in all the number pairs except one. Find that odd number pair.
Option 1: 5 : 128
Option 2: 3 : 30
Option 3: 7 : 352
Option 4: 1 : 4
Correct Answer: 7 : 352
Solution : Let's check the options – First option: 5 : 128→53 + 3 = 125 + 3 = 128 Second option: 3 : 30→33 + 3 = 27 + 3 = 30 Third option: 7 : 352→73 + 3 = 343
Question : The difference between the two numbers is 45% of their sum. The ratio of the larger number to the smaller number is:
Option 1: 20 : 9
Option 2: 9 : 20
Option 3: 29 : 11
Option 4: 11 : 29
Correct Answer: 29 : 11
Solution : Let the two numbers be $x$ and $y$. According to the information given, ($x$ – $y$) = ($x$ + $y$) × $\frac{45}{100}$ ⇒ 20$x$ – 20$y$ = 9$x$ + 9$y$ ⇒ 11$x$ = 29$y$ $\therefore x$ : $y$ = 29 : 11 So,
Question : ABC is an equilateral triangle points D, E and F are taken in sides AB, BC and CA respectively so that, AD = BE = CF. Then DE, EF, and FD enclose a triangle which is:
Option 1: equilateral
Option 2: isosceles
Option 3: right angled
Option 4: none
Correct Answer: equilateral
Solution : Given: ABC is an equilateral triangle points D, E and F are taken in sides AB, BC and CA respectively so that, AD = BE = CF. Now, AB = BC = CA and AD = BE = CF So, AD = BD = BE
