The correct answer is Option 2 i.e. 4/3% loss.

Profit = SP - CP

Loss = CP - SP

Profit% = (Profit × 100)/CP

Loss% = (Loss × 100)/CP

CP of first bicycle = Rs. 1600 and, SP of first bicycle = Rs.1280

CP of second bicycle = Rs. 1400 and, SP of second bicycle = Rs. 1680

For the first bicycle, CP > SP

So, Loss = 1600 - 1280 = Rs.320

For the second bicycle, SP > CP

So, profit = 1680 - 1400 = Rs.280

⇒ The overall Loss =  -320 + 280 = -40

Loss = Rs. 40

⇒ The total CP = 1600 + 1400 = Rs. 3000

⇒ Loss% = (40 × 100)/3000 = 4/3%

The correct answer is option 1 i.e. 70 m.

When both are running in opposite directions then, Relative speed = Sum of speeds of both

Also, Speed = distance/time

⇒ (31 + 5) × 5/18 = distance/7

⇒ 36 × 5/18 = d/7

⇒ 10 = d/7

⇒ d = 70

Hence length = 70 m

The correct answer is option 4 i.e. Both I and II are sufficient​​​.

According to the statement;

I. He turned his right and walked 2 km and reach the cafe.

II. The Cafe is 2 km north of the mall. A starts walking from the mall and walks around 4km and then reaches home.

Using statements I and II:

He turned his right and walked 2 km and reach the cafe. The cafe is 2 km north of the mall. A start walking from the mall to the east, walk around 4km, and then reach home.

Hence, the correct answer is Both I and II are sufficient.

The correct answer is option 1 i.e. IDZVS

Logic: Reverse the letters first, then write the next letter of each consonant and the opposite letter of each vowel. 

For the word BEAST:

Reverse: TSAEB

T + 1 = U

S + 1 = T

A ⇔ Z

E ⇔ V

B + 1 = C

So, BEAST = UTZVC

Similarly, for the word REACH: 

Reverse: HCAER

H + 1 = I

C + 1 = D

A ⇔ Z

E ⇔ V

R + 1 = S

So, REACH = IDZVS

Hence, the correct answer is IDZVS.

The correct answer is option 1 i.e. Abhyuday Jindal.

Abhyuday Jindal has recently been appointed as the new President of Indian Chamber of Commerce (ICC). He took over the leadership from Ameya Prabhu whose term ended on October 18, 2024. The ICC was established in 1925 with the aim to solve challenges faced by different industries.

The correct answer is Option 3 i.e. Hydrogen.

The element that does not belong to Group 1 of the Modern Periodic Table is Hydrogen. Although hydrogen is placed at the top of Group 1, it is not considered an alkali metal like Sodium, Lithium, and Rubidium, which are all part of Group 1. Hydrogen is a unique element with properties that differ significantly from those of alkali metals, making it distinct despite its position in the same column.

The correct answer is Option 2 i.e. 7.

At 25°C, a neutral solution has a pH of exactly 7. This is because the concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻) are equal in pure water, both being 1 × 10⁻⁷ M. A pH value of 7 indicates a balance between acidity and alkalinity, which is the hallmark of a neutral solution at this temperature. Other ranges indicate either acidic (pH < 7) or basic (pH > 7) solutions.

The correct answer is Option 3 i.e. Diffraction is a result of light bending around corners.

Diffraction is a phenomenon where waves, including light, spread out as they pass through an aperture or around obstacles. It occurs with both monochromatic and polychromatic light, and can produce patterns with single slits, multiple slits, or even with edges of objects. Unlike refraction or reflection, diffraction does not necessarily lead to the formation of a sharp image but rather to characteristic interference patterns or spreading of light waves.

The correct answer is Option 2 i.e. Stratified squamous epithelium.

The epithelial tissue type best suited for areas subject to friction is Stratified squamous epithelium. This tissue consists of multiple layers of cells, providing a robust protective barrier against mechanical stress and abrasion. The outermost layers can slough off without compromising the integrity of the tissue beneath, making it ideal for high-friction areas such as the skin's surface and the lining of the mouth, esophagus, and vagina. Its structure is specifically adapted to withstand continuous wear and tear.

The correct answer is Option 1 i.e. 1/378.

The highest common factor = H.C.F of numerators/L.C.M of denominators

H. C. F of 5, 9, and 12 = 1

L.C.M of 7, 14, and 27 = 378

The greatest common factor = 1/378
