Question : Directions: JMOP is related to GJLM in a certain way based on the English alphabetical order. In the same way, EHJK is related to BEGH. To which of the following is DGIJ related, following the same logic?
Option 1: ADFG
Option 2: ABEF
Option 3: AEFI
Option 4: ADFI
Correct Answer: ADFG
Solution : Given: JMOP is related to GJLM and EHJK is related to BEGH.
Subtract 3 from the place value of each letter of JMOP to obtain the required code – J – 3 = G; M – 3 = J; O – 3 = L; P
Question : If $\operatorname{cosec} \theta=1 \frac{7}{22}$, then find the value of $\cot ^2 \theta$.
Option 1: $\frac{49}{484}$
Option 2: $\frac{357}{484}$
Option 3: $\frac{225}{484}$
Option 4: $\frac{7}{22}$
Correct Answer: $\frac{357}{484}$
Solution : Given: $\operatorname{cosec} \theta=1 \frac{7}{22}$ ⇒ $\operatorname{cosec} \theta=\frac{29}{22}$ We know that: $\operatorname{cosec}^{2}\theta=\cot^{2}\theta+1$ ⇒ $\cot^{2}\theta=\frac{841}{484}–1$ ⇒ $\cot^{2}\theta=\frac{841–484}{484}$ ⇒ $\cot^{2}\theta=\frac{357}{484}$ Hence, the correct answer is $\frac{357}{484}$.
Question : Directions: Which term from among the given options can replace the question mark (?) in the following series to make it logically complete? D13Q, F17R, ?, J25T, L29U
Option 1: G22R
Option 2: G21S
Option 3: H22R
Option 4: H21S
Correct Answer: H21S
Solution : Given: D13Q, F17R, ?, J25T, L29U
In the above-given series, add 2 to the place value of the first letter, 4 to the number, and 1 to the place value of the third letter to obtain the next term. D13Q→D + 2 = F; 13

Question: Select the most appropriate option to fill in the blank number (2).
Option 1: founded
Option 2: found
Option 3: find
Option 4: had founded
Correct Answer: found
Solution : The correct choice is the second option.
The term "found" is suitable in this context because it suggests that the study discovered or observed the state of people's brains during these tasks. The passage is given in the past tense. So, the past form of

Question : If INR 2,000 is invested at a simple interest rate of 5% per annum and the interest is added to the principal after 10 years, then in how many years will it amount to INR 4,000 at the same rate of interest?
Option 1: $18 \frac{2}{3}$ years
Option 2: $16 \frac{1}{3}$ years
Option 3: $16 \frac{2}{3}$ years
Option 4: $18 \frac{1}{3}$ years
Correct Answer: $16 \frac{2}{3}$ years
Solution : Simple interest for 10 years = $\frac{\text{Principal × Rate × Time}{}}{100}$ = $\frac{\text{2000 × 5 × 10}{}}{100}$ = $1000$ Amount after 10 year = 2000 + 1000 = 3000 To get INR 4000 = 4000 – 3000 = 1000 is required. $\therefore$ Simple
Question : An engineering student has to secure 25% marks to pass. He gets 47 and fails by 43 marks. What are the maximum marks for the examination?
Option 1: 385 marks
Option 2: 410 marks
Option 3: 360 marks
Option 4: 435 marks
Correct Answer: 360 marks
Solution : Given: An engineering student has to secure 25% marks to pass. He gets 47 and fails by 43 marks. Passing marks = 47 + 43 = 90 If 25% is equivalent to 90 then, 100% is equivalent to (90 × 4) = 360 So,
