Accepted Answer

Each letter in the word is shifted forward by 3 positions in the English alphabet. Applying +3 to the letters of MATHS gives PDWKV.

Question 5

Average age of 20 students is 21 years. 2 students leave the group and 1 new student joins the group. The average now becomes 20 years. If age of one of the student who left the group is 26 years and the one who joined is 20 years, then what is the age (in years) of the other student who left the group?

Accepted Answer

Assuming the total number of students remains 20 for the math to work: Initial total = 420. New total = 400. Net decrease = 20. So, (26 + x) - 20 = 20, giving x = 14.

Question 6

Which of the following gas contributes the maximum to the phenomena of global warming?

Accepted Answer

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. While methane is more potent, CO2 is vastly more abundant, making it the largest contributor to global warming.

Question 7

Fire extinguishers emit which gas?

Accepted Answer

Fire extinguishers typically emit carbon dioxide (CO2) because it is heavier than oxygen. It displaces the oxygen around the fire, effectively smothering and extinguishing the flames.

Question 13

ΔXYZ is similar to ΔPQR. If ratio of perimeters of ΔXYZ : ΔPQR is 3:2 and if PQ = 6 cm then what is the length of XY (in cm)?

Accepted Answer

For similar triangles, the ratio of corresponding sides equals the ratio of their perimeters. Thus, XY/PQ = 3/2. Substituting PQ = 6 gives XY/6 = 3/2, so XY = 9 cm.

Question 14

Which among the following neighbouring country of India is the largest producer of Opium in the World?

Accepted Answer

Afghanistan is the world's largest producer of opium, historically accounting for the vast majority of the global supply due to its favorable climate and socio-economic conditions.

Accepted Answer

Using the formula SI = (P × R × T) / 100, we get 3200 = (P × 6.25 × 4) / 100. This simplifies to 3200 = P / 4, so P = 12800.
