The correct answer is option 2 i.e. 52 years.

The difference between Jaya's age and Divya's age

= 12 years

Let Jaya's age = 3x

& the Divya's age = 5x

A/Q,

5x - 3x = 12

⇒ 2x = 12

⇒ x = 12/2 = 6

So, the present age of Jaya and Divya is 18 years and 30 years, respectively.

The sum of their age after 2 years will be

= 18 + 2 + 30 + 2

= 52 years

The correct answer is option 2 i.e. Only conclusion II follows.

The least possible diagram would be

Conclusions:

I.  Some girls are boys. False (There is no definite relation between girls and boys so Some girls are boys It does not follow.)

II. Some engineers can be girls. True (This is a possible case and this possibility can be true because it does not affect any other relation and its possibility diagram would be like this:

So, only conclusion 2 follows.

Hence, the correct answer is Only conclusion II follows.

The correct answer is option 4 i.e. 66.

The pattern followed here is,

86 - 10 = 76

76 + 5 = 81

81 - 10 = 71

71 + 5 = 76

76 - 10 = 66

Hence, the correct answer is 66.

The correct answer is option 4 i.e. None of these.

Girls who are swimmers and play tennis are represented by the region common to the square, triangle and rectangle and no such region is given in the diagram which can represent only relationship of these three.

Hence, the correct answer is option 4.

The correct answer is Option 2 i.e. 69th.

• This legislation modifies the Government of the National Capital Territory of Delhi Act, 1991.

• Following the enactment of the 69th Constitutional Amendment Act, 1991, the Union Territory of Delhi is renamed as the National Capital Territory, and the official appointed under Article 239 shall be titled as the Lieutenant Governor.

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

• Green plants absorb approximately 1% of the solar energy that reaches their leaves for photosynthesis.

• The remaining 98 to 99% of solar energy, occurring at wavelengths unsuitable for photosynthesis, is reflected from leaves and other surfaces.

The correct answer is Option 3 i.e. Red

• From VIBGYOR - R (red) has the longest, and V(violet) has the shortest
• V- Violet
• I- Indigo
• B- Blue 
• G- Green
• Y- Yellow
• O- Orange
• R- Red

The correct answer is Option 1 i.e. Rubisco.

• In C3 plants, the enzyme responsible for catalyzing the reaction between carbon dioxide and ribulose-1,5-bisphosphate (RuBP) during the Calvin cycle is Rubisco, short for Ribulose-1,5-bisphosphate carboxylase/oxygenase.
• This enzyme plays a crucial role in fixing carbon dioxide from the atmosphere into an organic molecule, initiating the process of carbon fixation essential for carbohydrate synthesis.
• Rubisco is considered one of the most abundant proteins on Earth and is fundamental to photosynthetic carbon assimilation in plants.

The correct answer is option 1 i.e. Silicon.

Silicon (Si) does not belong to Period 6 of the Modern Periodic Table.

Explanation:

Period 6 in the periodic table comprises elements with atomic numbers ranging from 55 (Cesium, Cs) to 86 (Radon, Rn), including the lanthanide series. Silicon (Si), with an atomic number of 14, is situated in Period 3, not Period 6. It is a non-metal and a semiconductor that belongs to Group 14 (Carbon Group).

These elements have much higher atomic numbers compared to silicon and belong to a different period in the periodic table.

The correct answer is option 4 i.e. 1115.

1/x - 1/y = 11/24

⇒ (y - x)/xy = 11/24

⇒ -(x - y)/xy = 11/24

⇒ -11/xy = 11/24

⇒ xy = -24

⇒ x³ - y³ + x²y² = (x - y)³ + 3xy (x - y) + (xy)²

⇒ (11)³ + 3(-24) × 11 + 576

⇒ 1331 - 792 + 576

⇒ 539 + 576 = 1115
