Question : The least number which should be added to 8961 to make it exactly divisible by 84 is:
Option 1: 27
Option 2: 57
Option 3: 141
Option 4: 107
Correct Answer: 27
Solution : When 8961 is divided by 84, the quotient is 106, and the remainder is 57. The required number which should be added = Divisor $-$ remainder = 84 $-$ 57 = 27 Hence, the correct answer is 27.
Question : X is directly proportional to the square of Y. When X is 12, then Y is 2. Find the value of X when Y is 3.
Option 1: 30
Option 2: 9
Option 3: 27
Option 4: 18
Solution : $X\propto Y^2⇒ X = kY^2$ ⇒ $\frac{\mathrm{X{_1}}}{\mathrm{Y^2{_1}}} = \frac{\mathrm{X{_2}}}{\mathrm{Y^2{_2}}} $ ⇒ $\frac{12}{2^2} = \frac{\mathrm{X{_2}}}{3^2}$ ⇒ $\mathrm{X{_2}} = \frac{12}{4}\times 9$ ⇒ $\mathrm{X{_2}} = 27$ Hence, the correct answer is 27.

Question : Directions: Select the option figure that is embedded in the given figure (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 all the option figures, only the second option figure is embedded in the given question figure.
Hence, the second option is correct.
Question : In $\triangle PQR, PQ=QR$ and $O$ is an interior point of $\triangle PQR$ such that $\angle OPR=\angle ORP$. Consider the following statements: (i) $\triangle POR$ is an isosceles triangle. (ii) $O$ is the centroid of $\triangle PQR$. (iii) $\triangle PQO$ is congruent to $\triangle RQO$. Which of the above statements is/are correct?
Option 1: Only (i) and (ii)
Option 2: Only (i) and (iii)
Option 3: Only (ii) and (iii)
Option 4: Only (ii)
Correct Answer: Only (i) and (iii)
Solution : Given: In $\triangle PQR, PQ=QR$ and $O$ is an interior point of $\triangle PQR$ such that $\angle OPR=\angle ORP$. Since $PQ = QR$, so $\triangle PQR$ is an isosceles triangle. From the given data we cannot say that $O$ is the centroid
Question : Direction: Study the following bar diagram carefully and answer the question. The bar graph given below shows the foreign exchange reserves of a country (in million US dollars) from 1991– 1992 to 1998– 1999.
The percentage increase in the foreign exchange reserves in 1997– 98 over 1993– 94 is:
Option 1: 100%
Option 2: 150%
Option 3: 200%
Option 4: 120%
Correct Answer: 100%
Solution : The foreign exchange reserves in 1997–1998 were $5040$ million, as seen in the bar graph. 2520 million was the amount of foreign exchange reserves in 1993–94. Change in the number of reserves = $5040 - 2520= 2520$ Percentage increase = $\frac{\text{Difference}}{\text{The foreign exchange reserves in
