Question : The pie chart given below shows the production of 6 different factories. The total production of all these 6 factories is 15000. The production of a particular factory is shown as a percent of total production of all these 6 factories. $J_1$ = The value of average production of factories F3 and F6. $J_2$ = The difference between the production of factory F1 and F4. What is the value of ($J_2 – J_1$)?
Option 1: 385
Option 2: 395
Option 3: 375
Option 4: 305
Correct Answer: 375
Solution : Total production = 15000 Now let's calculate $J_1$ and $J_2$. $J_1$ = The value of average production of factories F3 and F6 $J_1$ = $\frac{\text{F3 } + \text{ F6}}{2}$ F3 = 6% of 15000 ⇒ F3 = 900 F6 = 5% of 15000 ⇒ F6
Question : The temperate grasslands of North America are known as
Option 1: Pampas
Option 2: Downs
Option 3: Steppes
Option 4: Prairies
Correct Answer: Prairies
Solution : The correct answer is Prairies.
Grasslands are large areas of grass that cannot support forests due to nutrient and water deficiencies. They are located between desert and forest ecosystems, and some examples of temperate grasslands and their locations include Prairies in North America, Pampas

Question : The residue left after extracting juice from sugarbeet and sugarcane is called
Option 1: molasses
Option 2: bagasse
Option 3: whey
Option 4: biomass
Correct Answer: bagasse
Solution : The correct option is - bagasse
The residue left after extracting juice from sugarbeet and sugarcane is called bagasse. Bagasse is the fibrous material that remains after the juice has been squeezed out, and it is primarily used as a biofuel or in the production
Question : Find the value of X for {15 × 32 ÷ 2 × 5} ÷ X=16
Option 1: 75
Option 2: 76
Option 3: 78
Option 4: 55
Correct Answer: 75
Solution : $\frac{15×32÷2×5}{X} = 16$ ⇒ $\frac{15×16×5}{X} = 16$ ⇒ $\frac{15×16×5}{16} = X$ ⇒ $75 = X$ Hence, the correct answer is 75.
Question : Which of the following organisms is most likely to produce greenhouse gases such as nitrous oxide and methane?
Option 1: Fungi
Option 2: Earthworm
Option 3: Bacteria
Option 4: Greenplants
Correct Answer: Bacteria
Solution : The correct option is Bacteria.
Bacteria are the organisms most likely to emit greenhouse gases such as nitrous oxide and methane. Certain bacteria, notably anaerobic bacteria, have been identified as key contributors to the creation of these gases during diverse biological activities. Methane (CH4) is
Question : If the circumference of a circle is 13.2 cm, then what is its radius?
Option 1: 1.7 cm
Option 2: 6 cm
Option 3: 21 cm
Option 4: 2.1 cm
Correct Answer: 2.1 cm
Solution : Given: Circumference of the circle = 13.2 cm Let the radius be $r$. We know the circumference of the circle = $2\pi r$ ⇒ $13.2 = 2\pi r$ ⇒ $13.2=2× \frac{22}{7}×r$ ⇒ $r = \frac{13.2\times 7}{2\times 22}$ ⇒ $r = 2.1$ cm Hence, the
Question : ______ - The time graph shows the speed of an object.
Option 1: Velocity
Option 2: Distance
Option 3: Displacement
Option 4: Acceleration
Correct Answer: Distance
Solution : The correct option is the Distance.
A distance-time graph shows the distance travelled by an object over time. A distance-time graph, also known as a position-time graph, is a graphical representation that shows how an object's position or distance changes over a specific period.
Question : 2 men can finish a work in 6 days and 3 women can finish the same work in 4 days. How many days will 1 man and 2 women finish the work if they work together daily?
Option 1: 4
Option 2: 6
Option 3: 8
Option 4: 9
Correct Answer: 4
Solution : Let Male = $m$; Female = $w$ Work = Rate $\times$ Time 2 men can finish the work in 6 days (assuming total work as 1 unit) $\therefore 2m\times 6 = 1$ ⇒ $m = \frac{1}{12}$ And 3 women can finish the same work in
Question : A sum of INR 1,00,000 was taken from a bank at the rate of 7% p.a to be compounded annually for 5 years. Calculate the compound interest. (Closest to an INR)
Option 1: INR 40,000
Option 2: INR 20,963
Option 3: INR 40,567
Option 4: INR 40,255
Correct Answer: INR 40,255
Solution : Given: Principal = INR 100000 Rate = 7% Time = 5 years We know that, $CI= P((1+\frac{R}{100})^{T}-1)$ $= 100000((1+\frac{7}{100})^{5}-1)$ $= 100000((\frac{107}{100})^{5}-1)$ $= 100000(\frac{14025517307}{10000000000}-1)$ $= 100000(\frac{14025517307-10000000000}{10000000000})$ $= 100000(\frac{4025517307}{10000000000})$ $= \frac{4025517307}{100000}$ $= 40255.17307$ = 40255 (Closest to an INR) Hence, the correct answer is INR 40255.
