Question : pH scale ranges______________.
Option 1: 1 to 14
Option 2: 1 to 7
Option 3: 0 to 14
Option 4: 0 to 7
Correct Answer: 0 to 14

Question : If [n] denotes the greatest integer < n and (n) denotes the smallest integer > n, where n is any real number, then the value of $(1\frac{1}{5})×[1\frac{1}{5}]-(1\frac{1}{5})+[\frac{1}{5}]+(1.5)$ is:
Option 1: 1.5
Option 2: 2
Option 3: 2.5
Option 4: 3.5
Correct Answer: 2
Solution : $(1\frac{1}{5}) × [1\frac{1}{5}] – (1\frac{1}{5}) + [\frac{1}{5}] + (1.5)$ = ($\frac{6}{5}) × [\frac{6}{5}] – (\frac{6}{5}) + [\frac{1}{5}] + (1.5)$ = (1.2) × [1.2] – (1.2) + [0.2] +(1.5) Applying floor and ceiling functions = 2 × 1 – 2 + 0 + 2 = 2
Question : The value of $x$ in the following equation is: 0.3 + 0.6 + 0.7 + 0.8 = $x$
Option 1: $5.3$
Option 2: $2\frac{3}{10}$
Option 3: $2\frac{2}{5}$
Option 4: $2.35$
Correct Answer: $2\frac{2}{5}$
Solution : Given: $0.3 + 0.6 + 0.7 + 0.8 = x$ $⇒x = 2.4 = \frac{24}{10} = \frac{12}{5}= 2\frac{2}{5}$ Hence, the correct answer is $2\frac{2}{5}$.
Question : The masculine aspect of the Manipuri classical dance is known as:
Option 1: Ras

Question : The ratio of the third proportional to 16 & 40 and the mean proportional between 10 & 40 is:
Option 1: 5 : 1
Option 2: 1 : 5
Option 3: 4 : 1
Option 4: 1 : 4
Correct Answer: 5 : 1
Solution : The third proportional to 16 and 40 is, = $\frac{(40)^2}{16}$ = 100 The mean proportional between 10 and 40 is, = $\sqrt{10 \times 40}$ = 20 The required ratio = 100 : 20 = 5 : 1 Hence, the correct answer is 5
Question : P and Q together can do a work in 12 days. P alone can do the same work in 18 days. In how many days can Q alone complete two-thirds part of the same work?
Option 1: 30
Option 2: 21
Option 3: 24
Option 4: 36
Correct Answer: 24
Solution : Time taken by P alone to complete a work = 18 days Part of work done by P alone in a day = $\frac{1}{18}$ Let $x$ be the time Q alone takes to complete a work. Part of work done by Q alone in a
Question : A boat can travel 104 km downstream in 8 hours. If the speed of the stream is 2 km/hr, then at what time will it be able to cover 13 km upstream?
Option 1: $2 \frac{2}{3}$ hours
Option 2: $1 \frac{4}{9}$ hours
Option 3: $2 \frac{1}{2}$ hours
Option 4: $1 \frac{2}{3}$ hours
Correct Answer: $1 \frac{4}{9}$ hours
Solution : Given, The boat can travel 104 km downstream in 8 hours. Speed of stream = 2 km/hr Let the speed of the boat in still water be $x$. So, $\frac{104}{(x + 2)} = 8$ ⇒ $x + 2 = 13$ $\therefore x= 11$
