Question 17: Each inch on ruler A is marked in equal $\frac{1}{8}$-inch units, and each inch on ruler B is marked in equal $\frac{1}{12}$-inch units.

b) 12

c) 18

d) 20

Question 19: Some students planned a picnic. The budget for food was Rs.500. But, 5 of them failed to go and thus the cost of food for each member increased by Rs 5. How many students attended the picnic ?

Question 20: The ratio between the rates of travelling of A and B is 2: 3 and therefore A takes 10 minutes more than the time taken by B to reach a destination. If A had walked at double the speed, he would have covered the distance in

a) 30 min

b) 25 min

c) 20 min

d) 15 min

The ratio of the number of students studying in schools A, B and C = 5: 6: 8.
Now, if the number of students in each of the schools is increased by 30% 25% and 25% respectively, the ratio = 5*1.3:6*1.25:8*1.25

= 6.5:7.5:10

= 13:15:20
Hence, the correct option is option B.

Now,
A:B = 1:3 = 15:45
B:C = 5:7 = 45:63
C:D = 9:7 = 63:49
Now, A:B:C:D = 15:45:63:49
Therefore, the correct option is option A.

Dry grapes contain 10% water.
Weight of dry grapes = 250kg
Therefore, weight of water part = 10% of 250 =kg
Weight of pulp part = 225 kg
Now, for fresh grapes to contain 80% water, 20% is pulp part.
20% of x = 225
x = 1225 kg
Therefore, the weight of grapes is = 1225kg

Side of triangle = 12 of  (1/8)th units = 12*(1/8) = 1.5 inches.
Now, x of (1/12)th units = 1.5 inches
Hence, x = 18.
Therefore, the correct answer is option A.

Let the common multiple be x.
Now, the materials cost is 234
Hence, (3/8)x = 234 i.e x = 624
Now, cost of labour = (4/8)x = (1/2) * 624 =312
Therefore, the correct option is option B.

Let the number of students be n and cost of food per student be x.
Now, 500/n = x
Also, lateron cost increases by 5when 5 students don’t come.
500/(n-5) = x+5
500/(n-5) = 500/n +5
Solving we get
n = 25
Hence, number of students attending picnic was 20.
