Each letter in the first term is shifted forward by 8 positions to get the second term (A+8=I, G+8=O, N+8=V). Applying this to BLM gives JTU.

Question 6

According to the Second Law of Motion, for a given force, acceleration is inversely proportional to the ____ of an object.

Accepted Answer

Newton's Second Law states F = ma. Rearranging this gives a = F/m. Therefore, for a constant force, acceleration is inversely proportional to the mass of the object.

Question 7

The ratio of present ages of P and Q is 7:9. Before 10 years the ratio of their ages was 5:7. What is Q's present age (in years)?

Accepted Answer

Let present ages be 7x and 9x. (7x - 10)/(9x - 10) = 5/7. Cross-multiplying gives 49x - 70 = 45x - 50, so 4x = 20, x = 5. Q's age = 9(5) = 45.

Accepted Answer

To convert binary 10110 to decimal, multiply each bit by powers of 2 from right to left: (1×16) + (0×8) + (1×4) + (1×2) + (0×1) = 16 + 0 + 4 + 2 + 0 = 22.

A can finish a work in 18 days and B in 36 days. If they work on it together for 9 days, then what percent of work is left?

Accepted Answer

Total work = LCM(18, 36) = 36 units. A's efficiency = 2, B's = 1. Together they do 3 units/day. In 9 days, they complete 27 units. Left work = 9 units, which is (9/36)*100 = 25%.

Accepted Answer

Since ∠B = 90° and ∠A = 60°, ∠C must be 30°. We need sec 30° × sin 60°, which is (2/√3) × (√3/2) = 1.
