Question : Directions: Which set of letters, when sequentially placed in the gaps in the given letter series, shall complete it? a_b_cc_a_b_c
Option 1: ababc
Option 2: aacbb
Option 3: abcab
Option 4: abbcc
Correct Answer: ababc
Solution : Given: a_b_cc_a_b_c
To fill in the blanks, divide the series into letter clusters – a_ b_ cc / _a _b _c Let's check each option – First option: ababc; aabbcc / aabbcc (aabbcc is repeated in
Question : At a certain sum of money with the interest rate of 6% per annum for 4 years, the simple interest is Rs. 4500. Find the compound interest (compounding annually) of 2 years at the same sum when the rate of interest is 4% per annum.
Option 1: Rs. 1,530
Option 2: Rs. 1,430
Option 3: Rs. 1,830
Option 4: Rs. 1,560
Correct Answer: Rs. 1,530
Solution : Simple Interest $= \frac{P\times R\times T}{100}$ ⇒ $4500 = \frac{P × 6 × 4}{100}$ ⇒ $P = \frac{4500 × 100}{6 × 4}$ ⇒ $P = 750 × 25 = \text{Rs. }18750$ Now, Compound Interest $= P(1 + \frac{R}{100})^T- P$ ⇒ $CI= 18750(1 + \frac{4}{100})^2

Question : If $3 \operatorname{cosec} A=7$, then what is the value of $\cos A \tan A$?
Option 1: $\frac{2 \sqrt{10}}{7}$
Option 2: $\frac{3}{7}$
Option 3: $\frac{4}{7}$
Option 4: $\frac{\sqrt{10}}{7}$
Correct Answer: $\frac{3}{7}$
Solution : Given: $3 \operatorname{cosec} A=7$ ⇒ $\operatorname{cosec} A=\frac{7}{3}$ ⇒ $\frac{1}{\sin A}=\frac{7}{3}$ ⇒ $\sin A=\frac{3}{7}$ $\therefore$ $\cos A \tan A=\cos A\times\frac{\sin A}{\cos A}=\sin A=\frac{3}{7}$ Hence, the correct answer is $\frac{3}{7}$.
Question : Directions: What will come in the place of the question mark (?) in the following equation if + and – are interchanged and × and ÷ are interchanged? 13 ÷ 145 × 29 – 79 + 17 = ?
Option 1: 119
Option 2: 131
Option 3: 124
Option 4: 127
Correct Answer: 127
Solution : Given: 13 ÷ 145 × 29 – 79 + 17 = ? After interchanging + and – and × and ÷, the new equation will be – = 13 × 145 ÷ 29 + 79 – 17 = 13 × 5 + 79 – 17

Option 1: IOT
Option 2: JPT
Option 3: IPT
Option 4: JOT
Correct Answer: IPT
Solution : Given: YZN, HDI, QHD, ZLY, ?
In the above-given series, add 9 and 4 to the place values of the first and second letters, and subtract 5 from the place value of the third letter, to obtain the next term. First letter of the series→Y
Question : Directions: Select the number from among the given options that can replace the question mark (?) in the following series. 141, 152, 143, 155, 145, 158, ?
Option 1: 147
Option 2: 162
Option 3: 148
Option 4: 161
Correct Answer: 147
Solution : Given: 141, 152, 143, 155, 145, 158, ?
The pattern is as follows –
So, 147 is the missing number of the series. Hence, the first option is correct.
Question : After excluding stoppages, the speed of the bus is 60 km/hr and after including stoppages, it is 45 km/hr. For how many minutes does the bus stop per hour?
Option 1: 10
Option 2: 9
Option 3: 12
Option 4: 15
Correct Answer: 15
Solution : The average speed (including stoppages) = 45 km/hr Distance = Speed × Time taken So in 1 hour, distance travelled = 45 km The average speed (excluding stoppages) = 60 km/hr At this speed, time is taken by bus to travel 45 km = $\frac{45}{60}=\frac{3}{4}$
