Question : Directions: Substitute the correct mathematical symbols in place of * in the following equation. 16 * 4 * 5 * 14 * 6
Option 1: ÷, –, =, ×
Option 2: –, ×, +, =
Option 3: ÷, ×, =, +
Option 4: ÷, +, =, –
Correct Answer: ÷, ×, =, +

Question : What sum of money should be invested to earn a simple interest of INR 5,040 in 3 years and 6 months at a 12% rate of interest per annum?
Option 1: INR 9,000
Option 2: INR 11,000
Option 3: INR 15,000
Option 4: INR 12,000
Correct Answer: INR 12,000
Solution : Simple Interest (SI) = INR 5,040 Time (T) = 3 years 6 months = 42 months Rate (R) = 12% Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ $⇒ 5040 = \frac{(\text{P} × 42 × 12)}{1200}$ $⇒42P = 504000$ $\therefore P = 12000$ Hence,
Question : P alone can complete a work in 15 days and Q alone can complete the same work in 12 days. They start the work together but after 3 days P leaves the work. How much time will Q take to finish the remaining work?
Option 1: 7.2 days
Option 2: 7.8 days
Option 3: 8.5 days
Option 4: 6.6 days
Correct Answer: 6.6 days
Solution : P alone can complete a work in 15 days. ⇒ P's 1 day's work = $\frac{1}{15}$ Q alone can complete the same work in 12 days. ⇒ Q's 1 day's work = $\frac{1}{12}$ So, (P + Q)'s 1 day's work = $\frac{1}{15}+\frac{1}{12}=\frac{3}{20}$ ⇒ (P
Question : Directions: Select the option that is related to the third letter in the same way as the second letter is related to the first letter: A : Z :: I : ?
Option 1: V
Option 2: S
Option 3: R
Option 4: T
Correct Answer: R
Solution : Given: A : Z :: I : ?
Like, A : Z→Z is the opposite letter of A. Similarly, follow the same pattern for I : ?→R is the opposite letter of I.
So, the required missing letter is R. Hence, the third option is
