Answers :
1) Answer: C
let the original sum = 100
For 1 yr = 40 + 40 + (40 × 40) / 100
= 96%
For 2 yrs = 96 + 96 + (96 × 96)/100
= 192 + 92.16
= 284.16%
Total sum after two years = 100 + 284.16 =384.16%
2) Answer: C
= ½ × 80/100 × 390
= 0.4 × 390
= 156
3) Answer: B
Ntotal=1800
No. of students in year 2011 ⇒ 2140
Ratio = 1800 : 2140
90: 107
4) Answer: D
MTotal=2330/5 = 466
5) Answer: D
Total students in year
2009 ⇒ 2180
2010 ⇒2270
2011 ⇒2140
2012 ⇒2260
2013 ⇒2290
Hence average no. of students was maximum in 2013.
6) Answer: B
∵ diagonal of rhombus intersect at right angle hence
AO = 3 cm ⇒ AC = 6 cm
Area of rhombus = ½ ×6 × 8 = 24 cm
7) Answer: C
Curved string = 2πr
= 18π cm
Straight string = 3 × (28) = 54 cm
Total length of string = 54 + 18π cm
8) Answer: B
(2π – 1) r = 111
(44/7–1) r = 111
37/7 r = 111
r = 21 cm
Area of circle = 22/7 × 21 × 21
=1386 cm2
9) Answer: A
d = 14 cm
r = 7 cm
C.S.A. of a sphere = 4πr²
= 4 × 22/7 × 7 × 7
= 616 cm2
10) Answer: D
