Answers :
1) Answer: C
At 8% rate interest will be = 248 Rs.
At 6% rate interest amount = 186 Rs.
2) Answer: C
% of people who read newspaper
= 30 × 2/5
= 12%
Total number of female who read newspaper A
= 12/100 × 20000
= 2400
3) Answer: D
Males reading newspaper B in terms of total people
= 20/1 × 2/5
= 8%
Male reading newspaper D in terms of % of total people
= 12 × 1/3
= 4%
Difference = (8 – 4)% ⇒ 4% of total people
⇒ 4/100 × 20000
= 800
4) Answer: C
No. of female in terms of % of total no. of people
5) Answer: B
Males reading newspaper C
= 16/8 × 3 = 6% of total
Females reading newspaper E = 14%
Hence
⇒ (14 – 6) / 6 ⇒ 133.33
6) Answer: C
ℓbh = 12ℓ × 1.2b × h’
h / 1.44 = h^’
0.69444h = h’
=30.55%
7) Answer: B
Area of base of cone = 38.5 = πr²
r = 3.5 cm
Vol. cone ⇒ ⅓ πr²h
154 = ⅓× 38.5h
h = 12 cm
ℓ = √(h2 + r2 )
â„“ = 12.5 cm
C.S.A. of cone = πr ℓ
= 22/7 × 3.5 × 12.5
= 11 × 12.5
= 137.5
If 2 cm is width of the canvas then total length required
= 137.5/2 = 68.75 cm
8) Answer: D
Vol. of sphere = 4/5 πr³
Radius of conical bullet = r’ = r/2
Height of conical bullet = h = r/2 = r/4
No. of bullets = n
n = 64
9) Answer: A
= 12 cm
Min difference between these two chord = 16 – 12 = 4cm
10) Answer: B
ℓb = 15ℓb’
.66b = b’
Reduction in the breadth is 33.33%
