Answer Key With Explanation

1.d

Let the first and last innings be x and y respectively,

x+y=38×68-36×65

x+y=244——(I)

x-y=24——(II)

Solve the equations I and II,

and we get, x=134

y=110

Therefore the last innings run =110

2.   a

Sum of the four persons weight=63×4=252

Ratio of four persons= 5 : 3 : 9 : 11

first persons weight=252/28×5=45 kg

Third person^’ sweight=252/28×9=81 kg

Average of 1st and 3rd persons weight=(45+81)/2=63 kg

3.c

Total marks of Dinesh,Kamalesh and Ramesh=84×3=252

Suresh’s mark=84-15=69

Dinesh’s mark=69+23=92

Kamalesh mark=92+5=97

Kamesh mark’s= (Total marks of Dinesh, Kamalesh and Kamesh)-(Dinesh + Kamalesh marks)

= 252-(92+97) = 63

Sum of Suresh, Dinesh’s and kamesh’s marks= 92 + 69 + 63 = 224

4.e

After 11 years Shakthi’s age=46 yrs

Present age of Shakthi=46-11=35 yrs

Sharmi’s age= 35+ 7=42

Susma’s age=42/7×5=30 yrs

Average age of Shakthi and Susma = (35+30)/2=32.5 yrs

5.b

Let as consider five numbers are P, Q, R, S, T and U

R=140/100×P

R=140/100×S

140/100×P=140/100×S

P/S=1/1

First number (P) is=30

R=140/100×30=42

Q=2/3×42=28

S=30

T=2P=60

U=80/100×30=24

Average of last three numbers=(30+60+24)/3=38

6.c

Average speed=2xy/(x+y)

=(2×x×45)/(x+45)=54

90x=54x+2340

36x=2340

x= 67.5 km/hr

7.d

According to the question,

((250×56000)+(x×52000))/(250+x)=54000

14000000+52000x=13500000+54000x

2000x=500000

x=250

Total employees=250+250=500

8.c

Sum of temperature of First 7 days=45°×7=315°

Sum of temperature of Last 7 days=57°×7=399°

Sum of temperature of 1 week=13×52°=689°C

7^th day temperature is= (315+399)-689=25°C

9.c

Ratio of the values,

=5×8 :7×5 :10×7

=40 : 35 : 70

= 8 : 7 : 14

10.b

Kavitha=7 yrs 6 month

Sharatha= 17 yrs 5 month

Sharath=11 yrs 10 month

Average=(36 yrs 9 month)/3

=(36 9/12)/3=121/4  years
