Question : Sudeep invested $\frac{1}{8}$th of a certain sum at 5% p.a. for two years and $\frac{3}{5}$th of the sum at 6% p.a. for two years and the remaining at 10% p.a. for two years. If the total interest received is INR 1,674, then the total sum invested is:
Option 1: INR 13,000
Option 2: INR 12,000
Option 3: INR 10,500
Option 4: INR 12,500
Correct Answer: INR 12,000
Solution : Let total sum be INR $x$. Remaining part $=x - \frac{x}{8} - \frac{3x}{5}=\frac{40x - 5x - 24x}{40}=\frac{11x}{40}$ According to the question ⇒ $\frac{(x × \frac{1}{8} × 5 × 2)}{100} + \frac{(x × \frac{3}{5} × 6 × 2)}{100} + \frac{(x × \frac{11}{40} × 10 ×
Question : A man read $\frac{2}{5}$th of a book on the first day. He read $\frac{1}{3}$rd more on the second day than he read on the first day. 15 pages were left for the third day. The number of pages in the book is:
Option 1: 100
Option 2: 105
Option 3: 225
Option 4: 250
Correct Answer: 225
Solution : Let the number of pages be $x$. Given: 1st day he read = $\frac{2x}{5}$ 2nd day = $\frac{2x}{5} + [\frac{2x}{5}\times\frac{1}{3}] = \frac{2x}{5} + \frac{2x}{15} = \frac{8x}{15}$ Remaining pages = $x - [\frac{2x}{5} + \frac{8x}{15}]$ = $x - \frac{14x}{15}$ = $\frac{x}{15}$ According to the question, $\frac{x}{15}$
Question : In a triangle ABC, if $\angle B=90^{\circ}, \angle C=45^{\circ}$ and AC = 4 cm, then the value of BC is:
Option 1: $\sqrt{2} \mathrm{~cm}$
Option 2: $4 \mathrm{~cm}$
Option 3: $2 \sqrt{2} \mathrm{~cm}$
Option 4: $4 \sqrt{2} \mathrm{~cm}$
Correct Answer: $2 \sqrt{2} \mathrm{~cm}$
Solution : AC = 4 cm $\angle B=90^{\circ}$ $\angle C=45^{\circ}$ $\therefore \angle A = 180^{\circ}-(90^{\circ}+45^{\circ}) = 45^{\circ}$ Since $\angle A= \angle C$, $AB = BC$ -----------(i) By Pythagoras theorem, $AB^2 + BC^2 = AC^2$ ⇒ $BC^2 + BC^2 = 4^2$ ⇒ $2BC^2 = 16$ ⇒
Question : A big cube is formed by arranging the 160 coloured and 56 non-coloured similar cubes in such a way that the exposure of the coloured cubes to the outside is minimal. The percentage of exposed area that is coloured is:
Option 1: 25.9%
Option 2: 44.44%
Option 3: 35%
Option 4: 46%
Correct Answer: 44.44%
Solution : Total number of cubes = 160 + 56 = 216 Thus, side of cube = $\sqrt[3]{216}$ = 6 unit No. of cubes without exposure = (6 – 2)3 = 64 Thus, 64 coloured cubes will not be exposed. Now, Number of coloured cubes on
Question : Directions: Arrange the given words in the sequence in which they occur in the dictionary. 1. Temple 2. Trained 3. Training 4. Troupe 5. Tented
Option 1: 15234
Option 2: 15243
Option 3: 15432
Option 4: 14532
Correct Answer: 15234
Solution : Given: 1. Temple 2. Trained 3. Training 4. Troupe 5. Tented
Step 1: Compare the first letter of each word. Since all the words start with the same letter T, then move to the next letter. Step 2: The second letter of each word
Question : The price of diesel increased by 16%. A person wants to increase his expenditure on diesel by 10% only. By what percentage, correct to one decimal place, should he reduce his consumption?
Option 1: 6.5%
Option 2: 5.2%
Option 3: 3.7%
Option 4: 4.5%
Correct Answer: 5.2%
Solution : Let the price of diesel and quantity be Rs.100 and 100 litres. Total expenditure = Rs.100 × 100 = Rs.10000 The price of diesel increased by 16%. New price = 100 + 16 = 100 He wants to increase his expenditure on diesel by 10%
Question : Which of the following is NOT a correct match?
Option 1: Voltage - volts
Option 2: Resistance - Ohm
Option 3: Conductance - siemens
Option 4: Capacitance - dyne
Correct Answer: Capacitance - dyne
Solution : The correct answer is Capacitance - dyne.
The capacitance unit measures a system's ability to store electric charge per unit voltage. It's called the farad (F). It indicates the ability of a substance to hold an electric charge. Dyne is the unit
