Answers:
1.Answer: B
Using the formulas
A=a2
P=4a
20 = 4a
a = 20÷4 = 5cm
Area = (a2) = 52 = 25cm2
2.Answer: C
Total weight of Girls = 20×40 = 800
Total weight of Boys = 30×60=1200
Average of Boys and girls = 2000/ 50 = 40
3.Answer: B
x – 12 = (70/100)x
100(x-12)= 70x
100x – 1200 = 70x
30x = 1200
X= 40
4.Answer: C
5.Answer: A
Product of two numbers = LCM × HCF
⇒ 320 = LCM × 8
⇒ LCM = 40
Ratio of HCF to LCM = 8 : 40 = 1 : 5
6.Answer: C
Sum of n natural no. = n(1+n)/2
= 35×36/2
=35×18 = 630
7.Answer: C
Loss on total deal,
= (Common loss or gain percentage /10)2 = (25/10)2
= 6.25% loss
8.Answer: D
Pipe A = 1/15
Pipe B = 1/ 30
A+B = 1/15 + 1/30 = (1/10)*6 = 6/10 = 3/5 tank filled
Remaining tank will be filled by B
Remaining tank= ( 2/5 )*30 =2*6 =12 minutes
9.Answer: C
tan45 °= 1
cot 45° = 1
1+1 =2
10.Answer: C
5 letter word can be arranged in 5 different ways = 5! / 2
