Answer :

Let age of the son before 1010 years =x=x and

age of the father before 1010 years =3x=3x

(3x+20)=2(x+20)

Age of the son at present =x+10=20+10=30

Age of the father at present =3x+10=3×20+10=70

Required ratio =70:30=7:3.

Question 5. The Ratio Between The Length And The Breadth Of A Rectangular Park Is 3:23:2. If A Man Cycling Along The Boundary Of The Park At The Speed Of 1212 Km/hr Completes One Round In 88minutes, Then What Is The Area Of The Park (in Sq. M)?

Answer :

Let length =3xkm,

breadth =2xkm

Distance travelled by the man at the speed of 1212 km/hr in 88 minutes =2(3x+2x)=10x

Therefore,

12×8/60=10x

x=4/25 km=160 m 

Area =3x×2x=6x2

=6×1602=153600 m2.

Question 8. A Batsman Makes A Score Of 87 Runs In The 17th Inning And Thus Increases His Averages By 3. What Is His Average After 17th Inning?

Answer :

Let the average after 17 innings = x

Total runs scored in 17 innings = 17x

Average after 16 innings = (x-3)

Total runs scored in 16 innings = 16(x-3)

Total runs scored in 16 innings + 87 = Total runs scored in 17 innings

=> sixteen(x-3) + 87 = 17x

=> 16x - forty eight + 87 = 17x

=> x = 39.

Question nine. The True Discount On A Bill Of Rs. 2160 Is Rs. 360. What Is The Banker's Discount?

Answer :

F = Rs. 2160

TD = Rs. 360

PW = F - TD = 2160 - 360 = Rs. 1800

True Discount is the Simple Interest on the present price for unexpired time

=>Simple Interest on Rs. 1800 for unexpired time = Rs. 360

Banker's Discount is the Simple Interest at the face fee of the bill for unexpired time

= Simple Interest on Rs. 2160 for unexpired time

=360/1800×2160=1/five×2160=Rs. 432.

Question 10. Tap 'a' Can Fill The Tank Completely In 6 Hrs While Tap 'b' Can Empty It By 12 Hrs. By Mistake, The Person Forgot To Close The Tap 'b', As A Result, Both The Taps, Remained Open. After 4 Hrs, The Person Realized The Mistake And Immediately Closed The Tap 'b'. In How Much Time Now Onwards, Would The Tank Be Full?

Answer :

Tap A can fill the tank completely in 6 hours

=> In 1 hour, Tap A can fill 1/6 of the tank

Tap B can empty the tank completely in 12 hours

=> In 1 hour, Tap B can empty 1/12 of the tank

i.E., In one hour, Tank A and B collectively can correctly fill (1/6-1/12)=1/12 tank

=> In 4 hours, Tank A and B can correctly fill 1/12×four=1/three×4=1/three of the tank.

Time taken to fill the remaining (1-1/3)=23(1-13)=2/3 of the tank =(2/3)(1/6)= four hours.

Question thirteen. A Boat Covers A Certain Distance Downstream In four Hours But Takes 6 Hours To Return Upstream To The Starting Point. If The Speed Of The Stream Be 3 Km/hr, Find The Speed Of The Boat In Still Water?

Answer :

Let the velocity of the water in nonetheless water = x

Given that speed of the move = three kmph

Speed downstream=(x+3) kmph

Speed upstream=(x-three) kmph

He travels a certain distance downstream in four hour and are available lower back in 6 hour.

Ie, distance travelled downstream in four hour = distance travelled upstream in 6 hour

for the reason that distance = velocity × time, we've

(x+three)4=(x-3)6

?(x+three)2=(x-3)three

?2x+6=3x-nine

?X=6+nine=15 kmph.

Question 14. What Day Of The Week Was 1 January 1901?

Answer :

1 Jan 1901 = (1900 years + 1st Jan 1901)

We understand that quantity of strange days in four hundred years = 0

Hence the variety of peculiar days in 1600 years = zero (Since 1600 is an excellent more than one of four hundred)

Number of strange days within the period 1601-1900

= Number of atypical days in 300 years

= five x 3 = 15 = 1

(As we can lessen ideal multiples of 7 from strange days with out affecting some thing)

1st Jan 1901 = 1 ordinary day

Total range of extraordinary days = (0 + 1 + 1) = 2

2 abnormal days = Tuesday

Hence 1 January 1901 is Tuesday.

Question 15. Today Is Thursday. The Day After 59 Days Will Be?

Answer :

59 days = 8 weeks 3 days = 3 abnormal days

Hence if these days is Thursday, After fifty nine days, it will be = (Thursday + three unusual days)

= Sunday

Hence January 1, 2005 = (Thursday + 2 unusual days) = Saturday.

Question 17. A Fort Had Provision Of Food For a hundred and fifty Men For 45 Days. After 10 Days, 25 Men Left The Fort. Find Out The Number Of Days For Which The Remaining Food Will Last?

Answer :

Given that fort had provision of food for one hundred fifty guys for forty five days

Hence, after 10 days, the remaining food is sufficient for a hundred and fifty men for 35 days

Remaining men after 10 days = one hundred fifty - 25 = one hundred twenty five

Assume that once 10 days,the ultimate food is sufficient for a hundred twenty five men for xx days

More guys, Less days (Indirect Proportion)

150 : a hundred twenty five :: x : 35

a hundred and fifty×35=125x

6×35=5X

X=6×7=42.

Question 20. A Boy Divided The Numbers 7654, 8506 And 9997 By A Certain Largest Number And He Gets Same Remainder In Each Case. What Is The Common Remainder?

Answer :

9997 - 7654 = 2343

9997 - 8506 = 1491

8506 - 7654 = 852

Hence, the best quantity which divides 7654, 8506 and 9997 and leaves equal remainder 

= HCF of 2343, 1491, 852

= 213

Now we need to find out the not unusual remainder.

Take any of the given numbers from 7654, 8506 and 9997, say 7654

7654 ÷ 213 = 35, remainder = 199.

Question 21. The Ratio Of Two Numbers Is four : five. If The Hcf Of These Numbers Is 6, What Is Their Lcm?

Answer :

Let the numbers be 4k and 5k

HCF of four and 5 = 1

Hence HCF of 4k and 5k = okay

Given that HCF of 4k and 5k = 6

=> ok = 6

Hence the numbers are (four × 6) and (5 × 6) 

= 24 and 30

LCM of 24 and 30 = 120.

Question 22. If Log10 five + Log10 (5x+1) = Log10 (x+5) + 1, Then X Is Equal To?

Answer :

log105 + log10 (5x+1) = log10 (x+5) + 1

=> log105 + log10(5x+1) = log10(x+five) + log10 10

=> log10[5(5x+1)] = log10[10(x+5)]

=> five(5x+1) = 10(x+5)

=> 5x+1 = 2(x+five)

=> 5x + 1 = 2x + 10

=> 3x = nine

=> x = three.

Question 23. A And B Started A Partnership Business. A's Investment Was Thrice The Investment Of B And The Period Of His Investment Was Two Times The Period Of Investments Of B. If B Received Rs 4000 As Profit, What Is Their Total Profit?
