1. 5
2. 10p^2 + 39p – 88 = 0

or, 10p^2 – 16p + 55p – 88 = 0

or, 2p(5p – 8) + 11(5p – 8) = 0

or, (2p + 11) (5p – 8) = 0

p = -11/2 or 8/5

1. 21q^2 + 41q – 40 = 0

or, 21q^2 + 56q – 15q – 40 = 0

or, 7q(3q + 8) – 5(3q + 8) = 0

or, (7q – 5) (3q + 8) = 0

q = 5/7 or -8/3

We can’t get specific relationship between p and q.

1. 1;
2. 14p^2 – 43p + 20 = 0

or, 14p^2 – 35p – 8p + 20 = 0

or, 7p(2p – 5) – 4(2p – 5) = 0

or, (7p – 4) (2p – 5) = 0

p = 4/7 or 5/2

1. 33q^2 + 72q + 12 = 0

or, 33q^2 + 6q + 66q + 12 = 0

or, 3q(11q + 2) + 6(11q + 2) = 0

or, (3q + 6) (11q + 2) = 0

q = -2 or -2/11

Hence, p > q.

1. 2
2. 56p^2 + 97p + 42 = 0

56p^2 + 49p + 48p + 42 = 0

or, 7p(8p + 7) + 6(8p + 7) = 0

or, (7p + 6) (8p + 7) = 0

p = -6/7 or -7/8

1. 99q^2 – 64q + 5 = 0

or, 99q2 – 9q – 55q + 5 = 0

or, 9q (11q – 1) – 5(11q – 1) = 0

or, (9q – 5) (11q – 1) = 0

or, (9q – 5) (11q – 1) = 0

q = 5/9 or 1/11

Hence, p < q.

1. 1
2. 16p^2 – 40p + 25 = 0

or, 16p^2 – 20p – 20p + 25 = 0

or, 4p(4p – 5) – 5(4p – 5) = 0

or, (4p – 5) (4p – 5) = 0

p = 5/4, 5/4

1. 25q^2 – 40q + 16 = 0

or, 25q^2 – 20q – 20q + 16 = 0

or, 5q(5q – 4) – 4(5q – 4) = 0

or, (5q – 4) (5q – 4) = 0

q = 4/5, 4/5

Hence, p > q.

1. 5
2. 15p^2 + 38p + 24 = 0

or, 15p2 + 20p + 18p + 24 = 0

or, 5p(3p + 4) + 6(3p + 4) = 0

or, (5p + 6) (3p + 4) = 0

p = -6/5 or -4/3

1. 20q^2 + 49q + 30 = 0

or, 20q^2 + 24q + 25q + 30 = 0

or, 4q(5q + 6) + 5(5q + 6) = 0

or, (4q + 5) (5q + 6) = 0

q = -5/4 or -6/5

Hence, we can’t get any specific relationship between p and q.

1. 5; The quantity of pure milk to be added

= {12 * (7 – 4)}/4 = 9 litres

1. 1

Suppose the present ages of P and Q are 4k and 5k respectively.

Then,

(4k + 6)/(5k + 6) = 7/8

Sum of the ages of P and Q

= 4k + 5k = 9k

= 9 × 2 = 18 years

1. 3

1. 2

1. 3

A’s, B’s and C’s 1 day work = 1/20 + 1/30 + 1/100

Total 3 day’s work = 28/300

Total 30 day work = 280/300

Remaining work = 20/300 = 1/15

Now A’s 1 day work = 1/20

Then remaining work = (1/60)/(1/30) = 1/2

Now, B’s then B complet the remaining work in 1/2

Total number of days = 31 1/2 days.
