1. raju is 19 yrs younger than his cousin. after 5 years, their ages will be in the ratio 2:3. find their present ages ????

i cant get this answer plsssssssssss solve it fast

a circular plot of ground of radius is 42m is surrounded by a circular ring of grss plot. find the width of a grass plot. if the area = that of the circular plot?

RAJU'S AGE = 33, HIS COUSIN'S AGE = 52

COUSIN'S AGE  = x

RAJU'S AGE = x - 19

AFTER 5 YRS., RATIO = 2/3

SO, (x - 19) + 5 / x + 5 = 2/3

x - 14 / x +5 = 2/3

3x - 42 = 2x + 10 (CROSS MULTIPLICATION)

SO, WE GET x = 52 SO, COUSIN'S AGE = 52 AND RAJU'S AGE = 52 - 19 = 33

let the cousin's age = x 

raju's age = x-19

afer 5 yrs he vratio = 2/3

so (x-19) + 5 / x +5 = 2/3

x-14 / x + 5 = 2/3

3x -42 = 2x +10 cross multiplication

Hence we get x=52 so the cousin's age is 52 and 52-19=33 so Raju's age = 33..

2nd que i didn't get...

Lets take Raju's cousin's age be x yrs

Therefore Raju's age = x-19

Ratio between Raju and his cousin=2:3

                                                =2/3

Hence (x-19) + 5/ x + 5 = 2/3

         =5+x-5+19/x+5=2/3

         =5+x-14/x+5=2/3

         =15+3x-42/2x+10

         =-37+3x=2x+10

         =-37-10=2x-3x

         =-47=-x

         =47=x

         =His cousin age after 5 yrs=47 + 5=52yrs

         =His age = 52-19=33

COUSIN 'S AGE = x

RAJU 'S AGE = x - 19

AFTER 5 YRS., RATIO = 2/3

SO,(x - 19)+ 5 /x +5 = 2/3

x- 14 /x +5 = 2/3

3x - 42 = 2x + 10 (CROSS MULTIPLICATION)

SO, WE GET x = 52 SO, COUSIN 'S AGE = 52 AND RAJU 'S AGE = 52 - 19 = 33
