• In Greek mythology, Hydaspes was a Pentapotamia river god with an extraordinary swift stream that flows into the Saronitic Syrtis.

Important Points

Greek Name of the remaining 4 rivers of Punjab -

First, find the normal rate of Pipe A:

• Pipe A fills 1000 liters in 150 minutes.
• Hence, its normal rate = 1000 / 150 = 6.6667 liters per minute.

Next, if it works at only 5% efficiency, its rate becomes:

• 5% of 6.6667 = 0.05 × 6.6667 = 0.3333 liters per minute (approximately).

Finally, to fill 60 liters at this reduced rate:

• Time required = 60 / 0.3333 ≈ 180 minutes.

Answer: 180 minutes (Option c).

Hence, Option C is correct.

Sum of 100 numbers =100×210=21000
Sum of 120 numbers =120×200=24000
Sum of 20 numbers =24000−21000=3000
∴ Average of 20 new numbers =3000/20=150

Hence, Option D is correct.

Step 1: Count Decimal Places in Each Number

• 95.75 has 2 decimal places

• 0.02554 has 5 decimal places

Step 2: Add the Decimal Places

When multiplying two decimals, the total number of decimal places in the product should be the sum of the decimal places in the two numbers:

2 (from 95.75) + 5 (from 0.02554) = 7 decimal places

Step 3: Check by Multiplying

Now let's multiply:

95.75 × 0.02554 = 2.445455

So the actual product has 6 digits after the decimal point — not 7.

Why the Difference?

Even though the rule says there should be 7 decimal places, trailing zeros are often dropped.
If the answer were 2.4454550, it would have 7 digits after the decimal, but since the zero is not significant, it's not written.

So the actual product is 2.445455, which has 6 digits after the decimal point.

Conclusion:

• Rule-based answer = 7 decimal places

• Actual product = 6 decimal places

Answer is: c) 6

According to the information given in the question, we can draw the following diagram.

BC = 24 m
FC = ED = 12 m
FC = 12 m
Thus point F is in the west w.r.t to point C and 12 m from point C.
Hence, the correct answer is "12 m west".

Clutch, Brake, Horn, and Steering are all components of a vehicle. Therefore, D is the appropriate choice.

Given figure are -

From option 1 - Doctor, Man, Student

Some doctor are man, some man are student, some doctor are student.

So It is the best representation of the venn diagram.

Let A  = Doctor, B = Man, C = Student

From option 2 - table, Chair, Furniture

No table is chair, some furniture are table as well as chair. It is not correct representation of the venn diagram.

From option 3 - Gold, silver, ornaments

It is not correct representation of the venn diagram.

From option 4 - Family, Parents, Children

 It is not correct representation of the venn diagram.

Hence, "option 1" is the correct answer.

The statement in option D is incorrect because, according to the passage:

• In cloning, the embryo is indeed transplanted into a surrogate mother.
• This step is a crucial part of the cloning process as described.

The radius of Mohr Circle ⇒ R=τ_max = √[(σ_x - σ_y/2)² + τ_xy 2)]

In static fluid,

τ_xy = 0 and σ_x = σ_y = - σ (normal compressive stress)

⇒ R=τ_max = √[(σ - σ/2)² + τ_xy 2 )] = 0

Therefore, Mohr Circle for Static Fluid is a Point Circle

Hence, the correct option is (D)

Hence, the correct option is (C).

Hence, the correct option is (B)

Grain size - 0.06 - 2mm

Hardness - variable, soft to hard, depends on clast and cement composition.

Colour - variable through a grey, yellow, red to white reflecting the variation in mineral content and cement.

Hence, the correct option is (D)

Hence, the correct option is (D)

Hence, the correct option is (C)

Basically, steel piles are a big screw, made of galvanized steel with a helical flange that not only helps to insert the pile, but also helps secure it into the ground. By using a mini-excavator with special attachments, a drill can enter the ground while measuring the load-bearing capacity of the soil.

Hence, the correct option is (D)

Fanning Plume- ELR inversion and Horizontal plume

Lofting- SALR above the inversion, so plume stays above the inversion

Fumigation- inversion occurs at a short distance from a stack, pollutants stay below the inversion layer.

Hence, the correct option is (D)

Backsight (BS) – short for "backsight reading", the first staff reading taken by the surveyor after the levelling instrument is set up and levelled. B.S is generally taken on the point of known reduced level as on the benchmark or a change point.

Hence, the correct option is (A)

Hence, the correct option is (B)

The construction target was achieved in the late 1950s. In 1956, a Highways Act was passed, and a second twenty-year plan proposed for the period 1961–1981, with the ambition of doubling road density to 32 km per 100 km². This second plan became known as the Bombay Road Plan.

Hence, the correct option is (B)

Hence, the correct option is (A)

Good brick earth should contain about 20% to 30% of alumina.

It is responsible for the plasticity characteristic of earth, which is important in a moulding operation.

If present in excess, then the raw brick shrinks and warps during drying.

Hence, the correct option is (C)

Biochemical oxygen demand (BOD) is the amount of dissolved oxygen needed (i.e. demanded) by aerobic biological organisms to break down organic material present in each water sample at certain temperature over a specific time period
