The present age of lewis and Brown are in ratio 1:2. Three years from now, the ages will in ratio 3:5. Find the age of lewis after five years?

Let's present age

Lewis =l

Brown=b

l/b=1:2

l-2b=0

After three years

l+3/b+3=3:5

5l-3b=6

l=6

b=12

After 5 years

l=11

b=17

In a ship provisions are sufficient for 700 men for 50 days. How long will these be sufficient for if there would have been 200 more men?

Let provision be sufficient for 200 men for x days

As men and days are inversely proportional to each other so,

X/50=700/1000

X=700/1000*50

X=35

Sushil was thrice as old as Snehal 6 years back. Sushil will be time as old as Snehal 6 years hence. How old is Snehal today.

let Snehal's age 6 years back =x

content, sushil's age 6 years back = 3x

(5 / 3)( x + 6 + 6 = (3 x + 6 + 6)

so 5 (x + 12 )= 3(3 X + 12)

so x = 6, Sanaya age = x+ 6

years = 12 years

John has 30 Marbles ,18 of which are red and 12 of which are blue. Jane has 20 Marbles all of them either red or blue. If the ratio of the red Marbles to the blue Marbles is the same for both John and jane, then John has how many more blue marbles than Jane?

John marble ratio:

read :blue

18 :12

3: 2

Jane Marbles are also with the same ratio as john.

Red: blue. total

3: 2. 20

3 X + 2 x = 20 = > 5 x = 20= >X = 4

2 X = 2( 4 )= 8 blue marbles

John have: 12 - 8 = 4 blue Marbles than jane
