Generally, we divide all economic activities into eight different industrial divisions. They are (i) Agriculture (ii) Mining and Quarrying (iii) Manufacturing (iv) Electricity, Gas and Water Supply (v) Construction (vi) Trade (vii) Transport and Storage and (viii) Services. For simplicity, all the working persons engaged in these divisions can be clubbed into three major sectors viz., (a) primary sector which includes (i) and (ii), (b) secondary sector which includes (iii), (iv) and (v) and (c) service sector which includes divisions (vi), (vii) and (viii).
I. (4x-5)3 + 1/(4x-5)3 = 2
II. 2[(y+1/y)2- 2]- 9(y+1/y)= -14
1.3wx = 40 – wy
2. b2 = 2b + p
3. d2 + d = q
Now, observe the given conditions:
I. 3p² - 17p + 22 = 0
II. 5q² - 21q + 22 = 0
Quantity I: The cash price of a notebook is Rs. 100 but is can also be purchased on 11 monthly equal instalments of Rs. 10 each. Find rate of S.I.?
...I: x2 - 33x + 242 = 0
II: y2 - 4y - 77 = 0
I. 3p2 - 11p + 10 = 0
II. 42q2 + q -1 = 0
I. x2 – 18x + 81 = 0
II. y2 – 3y - 28 = 0
I. 27x6-152x3+125=0
II. 216y6 -91y3+8=0
I. x² + 11x + 24 = 0
II. y² + 17y + 72 = 0
I. 2y² - 11 y + 15 = 0
II. 2x² + 3x – 14 = 0
