Q10. Before the arrival of Joe, a new partner, sales output in Bill’s company, Midas in Revere Ltd., had been rising by 10% per year on average. Innovations by Joe included computerization of technical processes and reductions in the work force, but annual sales output has only risen by 5% per year. It appears that Joe’s innovations have caused the reduction in the annual growth rate.
Which of the following, if true, would most seriously weaken the conclusions above?

(c) Joe’s innovations were intended as long-term investment and not made for short-term profit growth.
(d) General demand for the product manufactured by the company has declined.
(e) Workers laid off by Midas in Reverse Ltd. have been hired by a competitor who is taking an increasing share of the market.

Directions (11-15): There are two rows given and to find out the resultant of a particular row we need to follow the following steps: –
Step 1: If an even number is followed by an odd number then the resultant will be the addition of both the numbers.
Step 2: If an odd number is followed by a perfect square then the resultant will be the difference of that square number and the odd number.
Step 3: If an odd number is followed by another odd number (but not a perfect square) then the resultant will be the addition of both the numbers.
Step 4: If an odd number is followed by an even number (but not a perfect square) then the resultant comes by multiplying the numbers.
Step 5: If an even number is followed by another even number then the resultant will be the division of first number by the second number.

Solutions

S11. Ans(d)
Sol. For row-1:
An even number is followed by another even number = 20/4 = 5
An odd number is followed by another odd number (but not a perfect square) = 5 + 5 = 10
For row-2:
An odd number is followed by an even number (but not a perfect square) = 17×12 =204
An even number is followed by an odd number = 204 + 11 = 215
The sum is= 215+10=225

S12. Ans(c)
Sol. For row -1:
An odd number is followed by a perfect square = 21-9 = 12
An even number is followed by a even number = 12/6 = 2
For row – 2:
An even number is followed by another even number = 50/2 = 25
The resultant of row-2 is = 18-2 = 16
Then value of X must be = 9

S13. Ans(b)
Sol. For row – 1:
An odd number is followed by another odd number (but not a perfect square) = 25 + 7 = 32
An even number is followed by an even number = 32/16 = 2
For row – 2:
An even number is followed by an odd number = 8 + 17 = 25
An odd number is followed by an even number (but not a perfect square) = 25×12 = 300
The difference of row-1 and row-2= 300 – 2 =298

S14. Ans(b)
Sol. For row – 1:
An odd number is followed by another odd number (but not a perfect square) = 51 + 21= 72
An even number is followed by another even number = 72/4 = 18
For row – 2:
An even number is followed by an odd number = 16 + 17 = 33
An odd number is followed by another odd number (but not a perfect square) = 33 + 5 = 38
The multiplication of row-1 and row-2= 18 x 38 = 684

S15. Ans(b)
Sol. For row – 1:
An odd number is followed by an even number (but not a perfect square) = 7 x 8 = 56
An even number is followed by an odd number = 56 + 13 = 69
For row – 2:
An odd number is followed by a perfect square =16-5 = 11
An odd number is followed by a perfect square =11 – 9 = 2
The multiplication of row-1 and row-2= 69 + 2 = 71
