Answer Key-
Q-(1) Sol-(3)
l+b+h = 19 _____(I)
l2+b2+h2 = 125 _____(II)
Squaring equation (I)
(I+b+h)2 = 361
(I+b+h)2 – SA = (l2+b2+h2)
(l2+b2+h2) = 361 – 125
= 236 cm2
Q-(2) Sol-(2)
Age of new person = Age of one moved person – Number of persons × Decreased in average
= 20 – 24× 
= 20 – 8
= 12 years
Q-(3) Sol-(1)
No. of ways = 
Q-(4) Sol-(4)
Milk = 108 litre
Water = 72 litre
144+2x = 324
2x = 180
x = 90 litres
Q-(5) Sol-(5)
5p2 - 5p –3p + 3 =0
5p (p – 1) – 3 (p – 1) = 0
P = 1, 3/5
2q2 – 5q – 2q + 5 = 0
q (2q– 5)–1 (2q – 5)
q =5/2, 1
q > p
Q-(6) Sol-(1)
Q-(7) Sol-(3)
8p2 – 10 p + 3 = 0
8p2 – 6p – 4p + 3 = 0
2p (4p – 3) – (4p – 3)
p = 
2q2 + 5q + 3 = 0
2q2 + 3q + 2q + 3 = 0
q (2q + 3) +1 (2q +3) = 0
q = 
Q-(8) Sol-(1)
p2 – 4p – p+ 8 = 0
p (p – 4) – 2p (p – 4) = 0
p = 4 ,2
3q2 – 10 q + 7 = 0
3q2 –7q – 3q + 7 = 0
q (3q– 7)– 1(3q – 7) = 0
q = 
Relationship can't be determined
Q-(9) Sol-(5)
