Answers:

1). Answer: d

Sum of ages of 3 sisters=22×3=66

Ratio of their age=13:10:10

33x=66

X=2

Sum of ages of twin sisters=  20x=20*2=40

2). Answer: c

Average speed of bus and boat=(30+50)/2=40

Ratio of time=1:1

Distance by bus =30×3=90

Distance by boat=50×3=150

Ratio of distance of bus to boat=90:150=3:5

3). Answer:  a

Amount distributed=15×51=765

Total amount= 765+35=800

4). Answer: b

20% of CP of J= 25 % of CP of K

CP of (K/J)= 4/5

5). Answer: a

Ratio of water and liquor= 2:3

5x=60

X=12

Quantity of water=2x=2×12=24

Quantity of liquor=3x=3×12=36

(24+x)/(36-x)=1/1

X=6

6). Answer: d

2001/60×29=?x41

?=650

7). Answer: a

X+1/x=4

X2+1/X2=42-2=14

X4+1/X4=142-2=194

(X4+1/X4)(X4+1/X4)=x8+1/x8+2

x8+1/x8= 194×194-2=37634

8). Answer: a

Let the fraction be x And Its reciprocal be 1/x

2x+1/x=57/20

2x2+1=57x/20

40x2-57x+20=0

X=5/8

9). Answer: a

ab=14=>a=7,b=2

Substitute in a3+b3

73+23=343+8=351

Therefore, a+b=7+2=9

10). Answer: b

Compound ratio=2/7×5/6×1/5×7/9=1/27

11). Answer: a

In isosceles triangle two sides are equal.

Let x be the length of equal side

Hypotenuse of a right angled isosceles triangle=√2x=18

x=9√2
