Question 17

The average weight of P, Q and R is 47 kg. If the average weight of P and Q be 32.5 kg and that of Q and R be 48.5 kg, then what is the weight of Q (in kgs)?

Accepted Answer

Total weight of P, Q, R = 47 × 3 = 141 kg. P+Q = 32.5 × 2 = 65 kg. Q+R = 48.5 × 2 = 97 kg. Q = (P+Q) + (Q+R) - (P+Q+R) = 65 + 97 - 141 = 21 kg.

Question 18

What is the distance between the points (3 , 6) and (-2 , -6)?

Accepted Answer

Use the distance formula: √[(x2-x1)² + (y2-y1)²]. Here, √[(-2-3)² + (-6-6)²] = √[(-5)² + (-12)²] = √(25 + 144) = √169 = 13.

Question 19

A can make a cupboard in 10 days and B can do it in 50 days. Along with C, they did the job in 6.25 days only. Then in how many days C alone can do the job?

Accepted Answer

Let total work be 50 units. Efficiencies: A=5, B=1. A+B+C efficiency = 50/6.25 = 8. So, C's efficiency = 8 - 6 = 2. C alone takes 50/2 = 25 days.

Question 20

The force of friction between two surfaces will increase if:

Accepted Answer

Friction is directly proportional to the normal force pressing the surfaces together. Pressing the surfaces harder increases this normal force, thereby increasing the interlocking of irregularities and the friction.
