Q. If all the 10 numbers from A to J are positive integers then at least how many of them are even?
The table below gives all the possible values of B, C, D, E, F, G, H, l and J if the value of A is assumed to be 'x'
If, 'x' is even then A D. G and J are even. If 'x' is odd then B, C E F, H and I are even.
So, four numbers A, D, G and J are even.

Q. If all the 10 numbers from A to J are positive integers and A is equal to 1 then at a time at most how many of them can be perfect squares?
The table below gives all the possible values of B, C, D, E, F, G, H, l and J if the value of A is assumed to be 'x'
If x = 1, then a possibility is that B = 2, C = 4, D = 1, E = 2, F = 4, G = 1, H = 2, I = 4 and J = 1 in which case 7 values are perfect squares.
This is the maximum number of perfect squares which can occur at the same time i.e. in a single case.

Q. At FMS, what is the average salary of students, who did not get a PPO?
Total salary for FMS = 100 × 7 = ₹ 700 lakh
Total salary of PPO holders = (25% of 100) × 10
= 250 lakh
∵ Total salary of people not getting PPOs = 700 – 250
= 450
∵ Average annual salary of people not getting PPOs
= 450 / 75 = 6 lakhs.

Q. In 1999, how many companies have a profitability less than the average of the profitabilities of the four companies?
∴ Profitability = Profit / Revenue
Profitability of NIIT in 1999 = 106 / 481 = 0.2204
Profitability of Aptech in 1999 = 51 / 320 = 0.1594
Profitability of SSI in 1999 = 34 / 85 = 0.4
Profitability of Tata Infotech in 1999 = 6 / 420 = 0.0143
∴ Average of the profitabilities of the four companies in
∴ Only two companies Tata Infotech and Aptech have a profitability less than the average of the profitabilities in 1999.

Q. In 2002, if the cost in each company increased by 10% over 2001 and the revenue for each company decreased by 10% over 2001, what is the approximate profitability of all the companies taken together in 2002?
Total revenues of four companies in 2001 = 509 + 285 + 231 + 523
= 1548 crore
Total profit of four companies in 2001 = 20 + 54 + 51 + 27 = 152 crore
∵ Total cost = Revenue – Profit
∴ Total cost = (1548 – 152) = 1396 crore In 2002, total revenue ≈ (1548 – 155) crore
After decrease by 10% = 1393 crore.
Total cost = (1396 + 140) = 1536 crore
After increasing by 10%
Hence, net profit = (1393 – 1536) = – 143 crore
∴ Profitability = 143 / 1393 = 10.25%

Q. The completion of one cycle of the network results in one bottle ready to be sold in the market. The project involves a total of 800 bottles. What is the average cost of the entire project?
Average cost of each bottle = 5[3^{2} + 3^{2} + 4^{2 }+ 5^{2} + 3^{2} + 4^{2 }+ 3^{2} ]
= 5[9 + 9 + 16 + 25 + 9 + 16 + 9] = 5 x 93 = 465
Average cost of the project = 465 x 800 = 372000 .
