Question : As part of his journey, a person travels 120 km at 80 km/h, the next 100 km at 40 km/h, and returns to the starting point at 75 km/h. The average speed of the person throughout the journey is:
Option 1: 63.46 km/h
Option 2: 58.74 km/h
Option 3: 68.15 km/h
Option 4: 49.58 km/h
Correct Answer: 63.46 km/h
Solution : Time taken for the first journey $= \frac{120}{80} = \frac{3}{2}$ hr Time taken for the second journey $= \frac{100}{40} = \frac{5}{2}$ hr Distance covered in first and second journeys = 120 + 100 = 220 km While returning, the time taken $=\frac{220}{75 }= \frac{44}{15}$

Question : If $a+b+c=15$ and $\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=\frac{71}{abc}$, then the value of $a^{3}+b^{3}+c^{3}-3abc$ is:
Option 1: 160
Option 2: 180
Option 3: 200
Option 4: 220
Correct Answer: 180
Solution : Given: $a+b+c=15$ $\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=\frac{71}{abc}$ Taking LCM of (a, b, c), we have: ⇒ $\frac{bc+ac+ab}{abc}=\frac{71}{abc}$ ⇒ $bc+ac+ab=71$ We know that $a^{2}+b^{2}+c^{2}=(a+b+c)^{2}-2(ab+bc+ca)$ By putting the values, we have, $a^{2}+b^{2}+c^{2}=(15)^{2}-2×71$ ⇒ $a^{2}+b^{2}+c^{2}=225-142$ ⇒ $a^{2}+b^{2}+c^{2}=83$ We know that $a^{3}+b^{3}+c^{3}-3abc=(a+b+c)(a^{2}+b^{2}+c^{2}-(ab+bc+ca))$ By putting the values, we have, $a^{3}+b^{3}+c^{3}-3abc=(15)(83-71)$ Or, $a^{3}+b^{3}+c^{3}-3abc=15×12=180$ Hence, the
Question : A thief steals an item and escapes, running at a speed of 15 km/h. A policeman arrives at the spot of the crime after 4 minutes and immediately starts chasing the thief. 16 minutes after the policeman started to chase the thief, there was still a gap of 200 m between the two. At what distance from the spot of the crime will the policeman catch up with the thief and what is the speed of the policeman?
Option 1: 5.5 km; 16.5 km/h
Option 2: 6 km; 18 km/h
Option 3: 6.5 km; 19.5 km/h
Option 4: 5 km; 15 km/h
Correct Answer: 6 km; 18 km/h
Solution : Distance travelled by thief before police started chasing him = 15 × $\frac{4}{60}$ = 1 km Distance travelled by the thief in 16 minutes after police started chasing him = 15 × $\frac{16}{60}$ = 4 km In 16 minutes, the gap between
Question : ____________ measures the aggregate production of final goods and services taking place within the domestic economy during a year.
Option 1: Gross national income
Option 2: Gross domestic product
Option 3: Net national product
Option 4: National income at factor price
Correct Answer: Gross domestic product
Solution : The correct answer is Gross domestic product.
Gross Domestic Product (GDP) measures the aggregate production of final goods and services taking place within the domestic economy during a specific time, typically in a year. GDP is a key indicator of the overall
Question : Directions: By interchanging the given two signs which of the following equations will be not correct? + and ÷
Option 1: 18 + 6 – 6 ÷ 3 × 3 = 6
Option 2: 18 + 2 × 6 ÷ 3 – 7 = 50
Option 3: 7 × 8 ÷ 4 + 2 – 6 = 49
Option 4: 6 × 9 + 3 – 24 ÷ 8 = 2
Correct Answer: 7 × 8 ÷ 4 + 2 – 6 = 49
Solution : Given: Interchange + and ÷
First option: 18 + 6 – 6 ÷ 3 × 3 = 6 Interchanging + and ÷, and solving the L.H.S. we get, 18 ÷ 6 – 6 + 3
Question : If $k$ is the largest possible real number such that $p^{4}+q^{4}=(p^{2}+kpq+q^{2})(p^{2}-kpq+q^{2})$, then the value of $k$ is:
Option 1: $1$
Option 2: $–\sqrt{2}$
Option 3: $2$
Option 4: $\sqrt{2}$
Correct Answer: $\sqrt{2}$
Solution : Given: $p^{4}+q^{4}=(p^{2}+kpq+q^{2})(p^{2}-kpq+q^{2})$ -----(1) $p^{4}+q^{4}$ $=(p^{2})^{2}+(q^{2})^{2}$ $=(p^{2}+q^{2})^{2}-2p^{2}q^{2}$ $=(p^{2}+q^{2})^{2}-(\sqrt{2}pq)^{2}$ $=(p^{2}+\sqrt{2}pq+q^{2})(p^{2}-\sqrt{2}pq+q^{2})$ By comparing this with equation (1), we get, $k=\sqrt{2}$ Hence, the correct answer is $\sqrt{2}$.
