Accepted Answer

Sum the digits of both numbers and subtract the second sum from the first. For 55 % 4: (5+5) - 4 = 10 - 4 = 6.

Question 5

Select the correct option: Convert decimal 101 to binary .

Accepted Answer

Divide 101 successively by 2 and record the remainders. Reading the remainders from bottom to top gives 1100101. Thus, decimal 101 is 1100101 in binary.

Question 6

The weights of 4 boxes are 100, 90, 80 and 40 kilograms. Which of the following cannot be the total weight, in kilograms, of any combination of these boxes and in a combination a box can be used only once?

Accepted Answer

Check combinations: 100+90+80+40 = 310. 100+90+40 = 230. 90+80+40 = 210. No combination of these weights adds up to exactly 200.

Question 7

Which amongst the following is not a Cation?

Accepted Answer

A cation is a positively charged ion. Aluminium, copper, and zinc form positive ions (cations). Sulphate (SO₄²⁻) is a negatively charged ion, making it an anion.

Question 8

The weights of 4 boxes are 20, 40, 60 and 90 kilograms. Which of the following cannot be the total weight, in kilograms, of any combination of these boxes and in a combination a box can be used only once?

Accepted Answer

Check possible sums: 60+90=150, 20+60+90=170, and 20+40+60=120. However, no combination of the given weights (20, 40, 60, 90) adds up to exactly 160.

Question 9

In the following question, select the related letters from the given alternatives. JPSW : LQUX : : MRFT : ? JPSW : LQUX : : MRFT : ?

Accepted Answer

The pattern follows an alternating addition of +2, +1, +2, +1. Applying this to MRFT: M+2=O, R+1=S, F+2=H, T+1=U, which gives OSHU.

Question 10

There are 45 trees in a row. The lemon tree is 20th from right end. What is the rank of lemon tree from left end?

Accepted Answer

Total trees = 45. Rank from left = Total - Rank from right + 1. So, 45 - 20 + 1 = 25 + 1 = 26.

Question 11

Contact force is another name for _________.

Accepted Answer

Muscular force requires direct physical contact with an object to push or pull it. Therefore, it is fundamentally classified as a contact force, unlike magnetic or electrostatic forces.

Question 12

In what ratio is the segment joining (-1, 3)and (2,-4) divided by the Y axis?

Accepted Answer

The y-axis has an x-coordinate of 0. Using the section formula for the x-coordinate: 0 = (2m - 1n) / (m + n). This gives 2m = n, so the ratio m:n is 1:2.

Question 13

Which country did India lose to in the semi finals of the Men's Cricket World Cup 2015?

Accepted Answer

In the 2015 ICC Men's Cricket World Cup semi-final held in Sydney, Australia defeated India by 95 runs to advance to the finals, eventually winning the tournament.

The original question text is missing or corrupted in the source data, showing only a URL and date. The correct answer provided by the key is 20.

Question 15

What is the simpliﬁed value of (cos4 A – sin4 A)?

Accepted Answer

Use the difference of squares: (cos²A - sin²A)(cos²A + sin²A). Since cos²A + sin²A = 1, it simplifies to cos²A - sin²A, which is the standard identity for cos 2A.

Question 16

What is a bug in computer terminology? ?

Accepted Answer

In computer science, a bug is a flaw, mistake, or error in a computer program or system that causes it to produce an incorrect or unexpected result.

Question 17

The weights of 4 boxes are 70, 100, 20 and 40 kilograms. Which of the following cannot be the total weight, in kilograms, of any combination of these boxes?

Accepted Answer

Check combinations of the given weights. 70+100+20+40=230, 70+100+20=190, and 100+20+40=160. No combination adds up to exactly 200.

Question 18

A, B and C received an amount of Rs 8400 and distributed among themselves in the ratio of 6 : 8 : 7 respectively. If they save in the ratio of 3 : 2 : 4 respectively and B saves Rs 400, then what is the ratio of the expenditures of A, B and C respectively?

Accepted Answer

Incomes are 2400, 3200, and 2800 (from 8400 in 6:8:7). B's saving is 400 (2 units), so savings are 600, 400, 800. Expenditures = Income - Savings = 1800, 2800, 2000. Ratio is 9:14:10.

Question 19

A runner starts running from a point at 6:00 am with a speed of 8 km/hr. Another racer starts from the same point at 8:30 am in the same direction with a speed of 10 km/hr. At what time of the day (in p.m.) will the second racer will overtake the other runner?

Accepted Answer

The first runner travels for 2.5 hours, covering 20 km. The relative speed is 10 - 8 = 2 km/hr. Time to catch up = 20 / 2 = 10 hours. 8:30 am + 10 hours = 6:30 pm.

Question 20
