Q2. (2)
[5+22]
× 1 = 9,[9+32] × 2 = 36,[36+42] × 4 = 208,[208+52]
× 6 = 1398,[1398+62] × 8 = 11472
Q3. (3)
0.5+0.5 x 7=17;17 x 1+1 x 6=23;23 x 1.5+1.5 x 5=42;42 x 2+2 x 4=92

Q6. (2)
Sum of 8 numbers = 38.4 × 8 = 307.2
Sum of 7 numbers = 39.2 × 7 = 274.4
Therefore 8th number = 307.2 – 274.4 = 32.8
Q7. (1)
Let father's age be x year and son's age be y year.
According to question,
2(x+y) = 8y _______(I)
and = 28
or, x+y = 56 years__________(II)
From equation (I) and (II)
8 y = 112
y = 14 years, hence x = 42 years
Q8. (4)
2(l+b) = 46
(l + b)2 = (23)2
(l2 + b2 ) +2lb = 529
172 + 2lb = 529 => lb = 120
Area = l × b = 120 cm2
Q9. (3)
Water in 40 litres of mixture =
= 12 litres
= 12 litres
So, milk= 40 – 12=28 litres
Let x litres of milk be added to it –
According to question
x = 20
Milk to be added = 20 litres
