Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : As per the mirror image properties, closer things appear close to the mirror in the reflection. Here, according to the information provided, the mirror is placed on the right side of the figure (on Line AB). So, the left side of the reflected image will appear
Question : On dividing a number by 38, we get 90 as the quotient and 19 as the remainder. What is the number?
Option 1: 3401
Option 2: 3382
Option 3: 3458
Option 4: 3439
Correct Answer: 3439
Solution : Given: Divisor = 38, Quotient = 90 and Remainder = 19 We know, Dividend = (Divisor × Quotient) + Remainder = (38 × 90) + 19 = 3420 + 19 = 3439 Hence, the correct answer is 3439.
Question : If $\sqrt{\frac{\mathrm{a}}{\mathrm{b}}}=\frac{8}{3}-\sqrt{\frac{\mathrm{b}}{\mathrm{a}}}$ and $a-b=10$, then the value of $ab$ is:
Option 1: $32 \frac{1}{7}$
Option 2: $32 \frac{3}{7}$
Option 3: $32 \frac{4}{7}$
Option 4: $32 \frac{2}{7}$
Correct Answer: $32 \frac{1}{7}$
Solution : Given: $\sqrt{\frac{\mathrm{a}}{\mathrm{b}}}=\frac{8}{3}-\sqrt{\frac{\mathrm{b}}{\mathrm{a}}}$ ⇒ $\sqrt\frac{a}{b} + \sqrt\frac{b}{a} = \frac{8}{3}$ Squaring both sides, we have, ⇒ $\frac{a}{b}+\frac{b}{a}+2=\frac{64}{9}$ ⇒ $\frac{a^2 + b^2}{ab} = \frac{64-18}{9}$ ⇒ $a^2 + b^2 = \frac{46ab}{9}$ Now, $a-b=10$ Squaring both sides, ⇒ $a^2 + b^2 - 2ab = 100$ ⇒ $\frac{46ab}{9} - 2ab

Hence, the first option is correct.
Question : Rani's weight is 25% that of Meena's and 40% that of Tara's. What percentage of Tara's weight is equal to Meena's weight?
Option 1: 160%
Option 2: 140%
Option 3: 120%
Option 4: 100%
Correct Answer: 160%
Solution : 25% = $\frac{1}{4}$ So, Rani : Meena = 1 : 4 = 2 : 8 Now, 40% = $\frac{2}{5}$ So, Rani : Tara = 2 : 5 Now, the ratio of Rani : Meena : Tara = 2 : 8 : 5 Let the weight
Question : A, B and C started a business by investing INR 13,750, INR 16,250 and INR 18,750, respectively. If B's share in the profit earned by them is INR 5,200, what is the total profit (in INR) earned by them together?
Option 1: 18,200
Option 2: 17,500
Option 3: 15,600
Option 4: 16,600
Correct Answer: 15,600
Solution : Investment of A = INR 13,750 Investment of B = INR 16,250 Investment of C = INR 18,750 The ratio of investments = 13750 : 16250 : 18750 = 11 : 13 : 15 Let $x$ be the total profit. B's share of profit =
Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 63, 64, 60, 69, 53, ?
Option 1: 77
Option 2: 76
Option 3: 88
Option 4: 78
Correct Answer: 78
Solution : Given: 63, 64, 60, 69, 53, ?
In the above-given series, add and subtract alternately the square of the consecutive natural numbers. 63 + 12 = 63 + 1 = 64 64 – 22 = 64 – 4 = 60 60 + 3
Question : A shopkeeper allows a 20 percent discount on the marked price of an article and he suffers a loss of 5 percent. If the article is sold at marked price, then what will be the profit percentage?
Option 1: 8.33 percent
Option 2: 16.25 percent
Option 3: 18.75 percent
Option 4: 17.25 percent
Correct Answer: 18.75 percent
Solution : Here, MP denotes the marked price, CP denotes the cost price. Discount = 20% Loss = 5% $\frac{\text{MP}}{\text{CP}} = \frac{(100-\text{Loss})}{(100-\text{Discount})}$ ⇒ $\frac{\text{MP}}{\text{CP}} = \frac{(100-5)}{(100-20)}$ ⇒ $\frac{\text{MP}}{\text{CP}} = \frac{95}{80}= \frac{19}{16}$ If there is no discount, means discount = 0%, then profit % $\frac{\text{MP}}{\text{CP}} = \frac{(100+\text{Profit})}{(100-\text{Discount})}$
Question : Directions: Select the option figure in which the given figure (X) is embedded as its part (Rotation is NOT allowed).
Solution : Since the rotation is restricted, the embedded figure will have the same orientation as the main figure. By comparison of all the option figures, the given question figure is embedded only in the third option figure.
Hence, the third option is correct.
