Correct Answer: 92.8 km/hr

Solution : Time to travel from place X to place Y = 4 hours
Speed when travelling from place X to place Y = 80 km/hr
Distance from place X to place Y = 4 × 80 = 320 km
Time to travel from place Y to place Z = 1 hour
Speed when travelling from place Y to place Z = 80 × 180% = 144 km/hr
Distance from place Y to place Z = 144 × 1 = 144 km
Average speed = $\frac{\text{total distance}}{\text{total time}}$ = $\frac{320+144}{4+1}$ = $\frac{464}{5}$ = 92.8 km/hr
Hence, the correct answer is 92.8 km/hr.

Correct Answer: 1 crore

Solution : The correct option is 1 crore.

The upper limit of investment in plant and machinery for small-scale industries has been fixed at Rs. 1 crore.

The correct spelling of the word is "context". The word "contaxte" contains a spelling error with the wrong letter "a" instead of "e" and an extra "e" at the end.

Therefore, the correct spelling is context.

Correct Answer: effort

Solution : The correct choice is the second option.

Using the term effort suggests a conscious and dedicated endeavour on the part of the companies to establish a presence and communicate within the communities they operate in.

The meanings of the other options are as follows:

• An establishment is a place, organisation, or institution that has been founded and is typically involved in a specific activity, business, or service.

• An excuse is a reason or explanation offered to justify or pardon one's actions.

• An aisle is a passage between rows of seats in a building such as a theatre, church, or auditorium

Therefore, the complete sentence is: "All the companies make an effort to be seen and heard within communities."

Correct Answer: a, d, b, c

Solution : Given:
a. Centi b. Deca c. Kilo d. Deci

The arrangement of all the unit prefixes in increasing order is as follows –
Here all the words are unit prefixes of International Systems of Units (SI). According to the quantities, Centi comes first as Centi denote 10^-2 then Deci as Deci denote 10^-1, after that Deca denote 10 and at last Kilo denote 1000.
So, Centi→Deci→Deca→Kilo

The order is a, d, b, c. Hence, the third option is correct.

Correct Answer: Rs. 56,250

Solution : Given: A man sold an item for Rs. 33,750 and incurred a loss of 25%.
Here the selling price (SP) = Rs. 33,750
Loss percentage = 25%
So, the cost price (CP) = SP × $\frac{100}{100-\text{loss percentage}}$
= 33750 × $\frac{100}{100-25}$
= 33750 × $\frac{100}{75}$
= Rs. 45,000
Now to have a profit of 25%
SP = CP × $\frac{100+\text{profit percentage}}{100}$
= 45000 × $\frac{100+25}{100}$
= 45000 × $\frac{125}{100}$
= Rs. 56,250
Hence, the correct answer is Rs. 56,250.

Correct Answer: Coniferous forests

Solution : The correct answer is Coniferous forests.

According to the latitudinal extent, hilly areas are divided into Tundra and Taiga. Tundra is a snow-covered region that extends from 65 degrees to 90 degrees latitude, while taiga is a coniferous forest that is commonly found between 55 degrees to 65 degrees latitude. Examples of conifers are pine, fir, spruce, etc. Coniferous trees are rich in resin.

Correct Answer: 87

Solution : Given:
GANT is coded as 126, and PROM is coded as 186. 

Add the positional value of the alphabet of the given word and then multiply the resultant by 3.
GANT→7 + 1 + 14 + 20 = 42; 42 × 3 = 126
PROM→16 + 18 + 15 + 13 = 62; 62 × 3 = 186
Similarly, GAIL→7 + 1 + 9 + 12 = 29; 29 × 3 = 87

So, GAIL is coded as 87. Hence, the fourth option is correct.

Correct Answer: Maharashtra

Solution : The correct option is Maharashtra.

The extremely difficult economic circumstances that peasants faced were made worse in 1867 when the British colonial authority imposed a substantial 50% increase in land revenue. The Deccan Riots of 1875 were sparked by the increasing hardship of the rural population in Maharashtra caused by this increase in land revenue.

Correct Answer: INR 28500

Solution : Sum, $P$ = INR 12000
Simple interest, SI = INR 12000
Term, $n$ = 2 years
Let $R$ be the interest rate.
Simple interest = $\frac{\text{Principal × term × Rate}}{100}$
⇒ $12000 = \frac{12000 × 2 × R}{100}$
⇒ $R = \frac{100}{2} = 50$%
Term, $n$ = 3 years
When compounded annually,
Compound interest
= $P(1+\frac{R}{100})^n - P$
= $12000(1+\frac{50}{100})^3 - 12000$
= $12000(1+\frac{1}{2})^3 - 12000$
= $12000(\frac{3}{2})^3 - 12000$
= $12000(\frac{27}{8} - 1)$
= $12000×\frac{19}{8}$
= $28500$
Hence, the correct answer is INR 28500.
