Question : If $A=\frac{2}{3}+\frac{4}{7}$ of $\frac{14}{12}$ and $B=\frac{5}{12}$ of $\frac{7}{15} \times \frac{36}{21}$, then what is the value of $A + B$?
Option 1: $\frac{5}{3}$
Option 2: $2$
Option 3: $\frac{4}{3}$
Option 4: $\frac{2}{3}$
Correct Answer: $\frac{5}{3}$
Solution : $A=\frac{2}{3}+\frac{4}{7}$ of $\frac{14}{12}$ $=\frac{2}{3}+\frac{4}{7}\times\frac{14}{12}$ $=\frac{4}{3}$ $B=\frac{5}{12}$ of $\frac{7}{15} \times \frac{36}{21}$ $=\frac{5}{12}\times\frac{7}{15} \times \frac{36}{21}$ $=\frac{1}{3}$ $⇒ A + B =\frac{4}{3}+\frac{1}{3}= \frac{5}{3}$ Hence, the correct answer is $\frac{5}{3}$.
Question : If ${P}_1, {P}_2$, and ${P}_3$ are three distinct prime numbers, then what is the least common multiple of ${P}_1, {P}_2$, and ${P}_3$ ?
Option 1: $P_1$
Option 2: $P_1 \times P_2 \times P_3$
Option 3: $P_2 \times P_3$
Option 4: ${P}_1+{P}_2+{P}_3$
Correct Answer: $P_1 \times P_2 \times P_3$
Solution : The least common multiple (LCM) of three distinct prime numbers, P1, P2, and P3, is simply their product, $P_1 \times P_2 \times P_3$. To see why, we can use the fact that the LCM of any set of numbers is the
Question : If two successive discounts of 10% and 20% are offered, then what is the net discount?
Option 1: 22%
Option 2: 28%
Option 3: 25%
Option 4: 20%
Correct Answer: 28%
Solution : Single equivalent discount = $(a+b-\frac{a×b}{100}$)%, where $a$% and $b$% are successive discounts. Here, $a =10,b=20$ So, Single equivalent discount = $10+20-\frac{10×20}{100}=28$% Hence, the correct answer is 28%.
Question : The selling price of an article is Rs. 817. If the loss percentage is 14%, then what is the cost price of the article?
Option 1: Rs. 850
Option 2: Rs. 950
Option 3: Rs. 880
Option 4: Rs. 900
Correct Answer: Rs. 950
Solution : Let's denote the cost price of the article as $C$. The selling price ($SP$) is given as Rs. 817, and the loss percentage is 14% Loss Percentage = $\frac{\text{Cost Price – Selling Price}}{\text{Cost Price}}×100$ Given that the loss percentage is 14%. So, $14 =

Question : Select the number that will come in place of the question mark (?) in the following mathematical statement. $\left(9^2 \times 27+3^3 \times 7+?\right)^{\frac{1}{2}}=59$
Option 1: 1087
Option 2: 1105
Option 3: 1111
Option 4: 1090
Correct Answer: 1105
Solution : $\left(9^2 \times 27+3^3 \times 7+?\right)^{\frac{1}{2}}=59$ ⇒ $9^2 \times 27+3^3 \times 7+? = 59^2$ ⇒ $81 \times 27+27 \times 7+? = 3481$ ⇒ $2187+189+? = 3481$ ⇒ $? = 3481-2187-189 = 1105$ Hence, the correct answer is 1105.
