A potter asked his two sons to sell some pots in the market. The amount received for each pot was same as the number of pots sold. The two brothers spent the entire amount on some packets of potato chips and one packet of banana chips. One brother had the packet of banana chips along with some packets of potato chips, while the other brother just had potato chips. Each packet of potato chips costs 10/- and the packet of banana chips costs less than 10/-. The packets of chips were divided between the two brothers so each brother received equal number of packets. How much money should one brother give to the other to make the division financially equitable?

A machine produces a certain item at a rate of 200units per hour. The cost of each item produced is 6₹ and S.P is 12₹. None of the items are defective. If the rate of production is increased by y%, the no: of defective units become (4+0.05y)% and the cost of production of each item increases by (y/2)%. Find the profit (in ₹ per hour) if the machine production is 300 units per hour.

A rural child specialist has to determine the weight of five children of different ages. He knows from his past experience that each of the children would weigh less than 30 Kg and each of them would have different weights. Unfortunately, the scale available in the village can measure weight only over 30 Kg. The doctor decides to weigh the children in pairs. However, his new assistant weighed the children without noting down the names. The weights were: 35, 36, 37, 39, 40, 41, 42, 45, 46 and 47 Kg. The weight of the lightest
child is:

  1. A 15 31%
  2. B 16 25%
  3. C 17 29%
  4. D 18 13%
  5. E 20 1%

As each child appears for four times in the given ten pairs,

Sum of the weights of the five children = 408 / 4 = 102

Let weight of the lightest child and that of hevaiest child be x

and y

Then the weight of the second lightest child = 35 - x

The weight of the third lightest child = 36 - x

The weight of the second heaviest child = 47 - y

(x + 35 - x + 36 - x + y + 47 - y) = 102

=> x = 16

The graph of the cost of providing school dinners versus the number of children is a straight line not passing through the origin and increases as the number of pupils increases. For 200 students the cost is Rs. 9 each, for 300 students the cost is Rs. 8 each. The cost per student can never be below.

  1. A 8 15%
  2. B 7 30%
  3. C 6 55%

From the first case, total cost = 200 * 9 = 1800
and, 1800 = 200x + C, where C is a constant
Similarly, 2400 = 300x + C
Solving the equations, x = 6 and C = 600
Total Cost = 6N + 600, where N is the number of students
Average cost = (6N + 600) / N = 6 + (600 / N)
The minimum value for this = 6

A book was sold for a certain sum and there was a loss of 20%. Had it been sold for Rs. 3 more, then there would have been a profit of 30%. If it was sold for Rs. 6.60, then the profit/loss percentage would have been.

  1. A profit 10% 79%
  2. B loss 10% 21%
