Question 14

Two cyclists P and Q cycle at 20 km/hr and 25 km/hr towards each other. What was the distance (in kms) between them when they started if they met after 56 minutes?

Accepted Answer

Since they move towards each other, relative speed is 20 + 25 = 45 km/hr. Time is 56/60 hours. Distance = Speed × Time = 45 × (56/60) = 42 km.

Question 15

If 19#13=3; 25#3=11; 36#10=13; then what is the value of 7#3=?

Accepted Answer

The pattern is (First Number - Second Number) / 2. For example, (19 - 13) / 2 = 3. Applying this to 7#3 gives (7 - 3) / 2 = 2.

Question 16

Point A (4 , 2) divides segment BC in the ratio 2:5. Co-ordinates of B are (2 , 6) and C are (7 , y). What is the value of y?

Accepted Answer

Using the section formula for the y-coordinate: y = (my₂ + ny₁)/(m+n). Substituting the values gives 2 = (2y + 5×6)/(2+5). Solving 14 = 2y + 30 yields y = -8.

Question 17

If 2/3(6x/5 - 1/4) + 1/3 = 9x/5, then what is the value of x?

Accepted Answer

Expand the bracket: 4x/5 - 1/6 + 1/3 = 9x/5. Simplify the constants to get 4x/5 + 1/6 = 9x/5. Subtract 4x/5 from both sides to find x = 1/6.
