Q1. What Should Be Added To Each Term Of The Ratio 7: 13 So That The Ratio Becomes 2: 3 ?

Let the quantity to be brought be x

Then

7+x13+x=23

(7+x)three=2(thirteen+x)

3x-2x=26-21

x=5

Hence the specified number is 5

Q2. Two Numbers Are In The Ratio three:

Let the required numbers be 3x and 5x

If eight is delivered to each other

3x+8:5x+8=2:three

3x+85x+8=23

3(3x+eight)=2(5x+8)

9x+24=10x+sixteen

10x-9x=24-sixteen

x=8

Thus the numbers are 3x=three(eight)=24

5x=5(8)=forty

Q16. If A Man Travels With 5/6th Of His Usual Speed, He Is Late By 15 Mins. What Is The Usual Time Taken To Travel ?

Suppose guy's common velocity = s, and common time = t 

So distance = speed *time ==> d= s*t

If he travels with five/6th of his normal velocity that's = s*5/6

And time= (t+15) and distance, d = (s*5/6)*(t+15) as distance could be same 

s*t = (s*five/6)*(t+15) 

t= (5t+75)/6

t= 75 min.

Q29. In How Many Ways Letters Of World "main" Can Be Arranged, So That Vowels Always Come Together ?

LEADING word may be written as "L" "E" "A" "D" "I" "N" "G"

Taking vowels together = E A I, so vowels may be organized as= !3 approaches and we could Vowels be a unit X

So X L D N G, It may be arranged in = !5 Ways 

So whole word can be written in= !Three *! Five = 720 methods

Q30. A And B Can Complete A Work In 30 Days, Working Together. Both Worked For 20 Days And Then B Left The Work. The Remaining Work Was Completed By A Alone In 20 More Days. So In How Many Days B Alone Can

(A+B)'s 1-day work, whilst running together= 1/30

(A+B)'s 20 days' paintings= 20/30==> 2/three 

Remaining paintings = (1-2/three) ===> 1/3

Remaining paintings became performed through A in 20 more days = 1/three

So A can entire the entire paintings by myself in = 20* 3 ===>60 days 

Hence A's 1-day work, operating alone = 1/60

B?S 1 day paintings, working by myself = 1/30-1/60======1/60 

So B will take 60 days to for completing the whole word.
