Question : Depression formed due to deflating action of winds are called
Option 1: Playas
Option 2: Yardang
Option 3: Ventifacts
Option 4: Sand dunes
Correct Answer: Yardang
Solution : The correct option is Yardang.
Yardangs are geological formations generated in dry or desert locations by the deflating effect of wind. They are the consequence of abrasive wind-blown particles selectively eroding soft or easily erodible sedimentary material. When prevailing winds erode weaker areas of the
Question : The sum of the interior angles of a regular polygon A is 1260 degrees and each interior angle of a regular polygon B is $128 \frac{4}{7}$ degrees. The sum of the number of sides of polygons A and B is:
Option 1: 17
Option 2: 16
Option 3: 19
Option 4: 18
Correct Answer: 16
Solution : The sum of the interior angle Polygon A = 1260° If the sides of the polygon A are nA. ⇒ (nA – 2) × 180° = 1260° ⇒ (nA – 2) = $\frac{1260°}{180°}$ = 7 ⇒ nA = (7 +
Question : Directions: Select the related letter cluster from the given alternatives. BDFH : YWUS :: JLNP : ?
Option 1: QOMK
Option 2: ACEF
Option 3: ZXUT
Option 4: UVWX
Correct Answer: QOMK
Solution : Given: BDFH : YWUS :: JLNP : ?
Like, BDFH : YWUS→(BY, DW, FU, HS) are opposite pairs. Similarly, for JLNP : (?)→(JQ, LO, NM, PK) are opposite pairs.
Thus, JLNP is coded as QOMK. Hence, the first option is correct.
Question : Directions: Select the option figure in which the given figure (X) is embedded as its part (rotation is NOT allowed).
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Since the rotation is restricted. So, the embedded figure will have the same orientation as the main figure. By comparison of the question figure with all the option figures, the given question figure is embedded only in the second option figure.
Hence, the second option is

Option 3: Sumesh requested to Raman to please lend him some money as he needed it urgently.
Option 4: Sumesh requested Raman to lend me some money as I needed it urgently.
Correct Answer: Sumesh requested Raman to lend him some money as he needed it urgently.
Solution : The correct choice is the first option.
The steps for conversion are as follows:
Question : Sentences of a paragraph are given below in jumbled order. Arrange the sentences in the correct order to form a meaningful and coherent paragraph. A. The temperature of the world has increased, resulting in global warming. B. The melting of the ice caps will increase the sea level, thereby drowning many islands and coastal regions. C. The increased amount of carbon emission is considered as the reason behind global warming. D. The increase in the global temperature is melting the polar ice caps.
Option 1: ABCD
Option 2: ACBD
Option 3: ACDB
Option 4: BADC
Correct Answer: ACDB
Solution : The third option is correct.
Here, the given sentences discuss the progression and consequences of global warming. So, the logical flow of the sequence would be:
Question : If the seven-digit number 52A6B7C is divisible by 33, and A, B, and C are primes, then the maximum value of 2A + 3B + C is:
Option 1: 32
Option 2: 23
Option 3: 27
Option 4: 34
Correct Answer: 23
Solution : 5 + 2 + A + 6 + B + 7 + C = 20 + A + B + C Possible values of (A + B + C) = 1, 4, 7, 10, 13, 16, 19, 22, 25 Again, 5 + A + B
Question : Direction: Study the bar graph given below, which shows the percent distribution of total expenditures of a company under various expenses, and answer the question.
If the interest on loans amounted to INR 2.45 crores, then the total amount of expenditure on advertisement, taxes, and research and development is:
Option 1: INR 7 crores
Option 2: INR 4.2 crores
Option 3: INR 5.4 crores
Option 4: INR 3 crores
Correct Answer: INR 4.2 crores
Solution : Let the total expenditure be INR $100x$. According to the question, Interest on Loans = 17.5% $\frac{17.5}{100} \times 100x = 24500000$ $⇒17.5x=24500000$ $⇒x=1400000$ Total expenditure = 14,00,00,000 Expenditure on advertisement = 15% Expenditure on taxes = 10% Expenditure on research = 5% Total
Question : Directions: In this question, some equations are solved based on a certain system. On the same basis, find out the correct answer out of the four alternatives for the unsolved equation. If 6 × 2 × 9 = 269, 8 × 7 × 1 = 781, then 4 × 1 × 3 = ?
Option 1: 431
Option 2: 413
Option 3: 341
Option 4: 143
Correct Answer: 143
Solution : Given: 6 × 2 × 9 = 269; 8 × 7 × 1 = 781
The third number remains at the third position while the first and second numbers swap positions. Like, 6 × 2 × 9 = 269 And, 8 × 7 × 1
Question : What is the ratio of the mean proportional between 1.6 and 3.6 and the third proportional of 5 and 8?
Option 1: 2 : 15
Option 2: 5 : 16
Option 3: 3 : 16
Option 4: 4 : 15
Correct Answer: 3 : 16
Solution : Mean proportion of 1.6 and 3.6 $=\sqrt{ab}=\sqrt{1.6\times 3.6}=2.4$ Now, the third proportion of 5 and 8 $=\frac{b^2}{a}=\frac{8^2}{5}=\frac{64}{5}$ $\therefore$ Ratio of mean proportion to third proportion = $2.4:\frac{64}{5}$ = 12 : 64 = 3 : 16 Hence, the correct answer is 3 : 16.
