Question : R, S, and T can finish a work in 20,15, and 10 days, respectively. R works on all days and S and T work on alternate days with T starting the work on the first day. In how many days is the work finished?
Option 1: $\frac{61}{7}$
Option 2: $\frac{50}{7}$
Option 3: $\frac{52}{7}$
Option 4: $\frac{57}{8}$
Correct Answer: $\frac{52}{7}$
Solution : Given: R alone can complete a task in 20 days. T alone can complete the same task in 15 days. S alone can complete the same task in 10 days. Total work is LCM of 20,15 and 10 = 60 units So, the efficiency of

Question : If $x-\frac{1}{x}=5, x \neq 0$, then what is the value of $\frac{x^6+3 x^3-1}{x^6-8 x^3-1} ?$
Option 1: $\frac{3}{8}$
Option 2: $\frac{13}{12}$
Option 3: $\frac{4}{9}$
Option 4: $\frac{11}{13}$
Correct Answer: $\frac{13}{12}$
Solution : Given: $x-\frac{1}{x}=5$ Cubing both sides, we get $(x-\frac{1}{x})^3=5^3$ ⇒ $x^3-\frac{1}{x^3}-3(x\times\frac{1}{x})(x-\frac{1}{x})=125$ ⇒ $x^3-\frac{1}{x^3}-3\times5=125$ ⇒ $x^3-\frac{1}{x^3}=140$ Thus,$\frac{x^6+3 x^3-1}{x^6-8 x^3-1}$ Taking $x^3$ as common, we get: = $\frac{x^3+3-\frac{1}{x^3}}{x^3-8-\frac{1}{ x^3}}$ = $\frac{x^3-\frac{1}{x^3}+3}{x^3-\frac{1}{ x^3}-8}$ Putting the values, we get: = $\frac{140+3}{140-8}$ = $\frac{143}{132}$ = $\frac{13}{12}$ Hence, the correct answer is

Question : A sold a horse to B for Rs. 4800, losing 20%. B sells it to C at a price that would have given A a profit of 15%. B's gain is:
Option 1: Rs. 1,800
Option 2: Rs. 1,900
Option 3: Rs. 2,000
Option 4: Rs. 2,100
Correct Answer: Rs. 2,100
Solution : Selling price by A = Rs. 4,800 Loss = 20% of Cost price Selling price = Cost price – loss Rs. 4,800 = 80% of Cost price ⇒ Cost price by A = $\frac{4800}{0.8}$ = Rs. 6,000 Profit = 15% of Cost price by
Question : What is the product formed when sodium Bicarbonate is heated strongly?
Option 1: Sodium carbonate
Option 2: Sodium hydroxide
Option 3: Sodium peroxide
Option 4: Sodium monoxide
Correct Answer: Sodium carbonate
Solution : The correct option is Sodium carbonate.
When sodium bicarbonate (baking soda) is heated to high temperatures, it undergoes a chemical reaction and decomposes into three separate compounds: sodium carbonate (soda ash), water, and, carbon dioxide gas. This reaction's chemical equation is 2NaHCO3
Question : A thief steals a bike at 12:30 p.m. and drives it at 48 km/hr. But the theft is discovered after half an hour. The bike owner starts to chase him on another bike at 58 km/hr. The thief will be caught at ________.
Option 1: 3:40 p.m.
Option 2: 3:54 p.m.
Option 3: 3:10 p.m.
Option 4: 3:24 p.m.
Correct Answer: 3:24 p.m.
Solution : Speed of thief = 48 km/hr Distance travelled by him in 30 mins = $48\times \frac{30}{60}=24$ km Owner speed = 58 km/hr Their relative speed = 58 – 48 = 10 km/hr Time = $\frac{\text{Distance}}{\text{Speed}}$ = $\frac{24}{10}=2.4\ \text{hours}$ = 2 hours 24 minutes The
