Question

Present ages of Ramu and Raghu are in the ratio 4:5 eight years from now the ratio of their ages will be 5:6. Find their present ages.'

Answer 1

Answer:

so let's go then,

so after 8 yrs, means, if we take ratio of 4a+8 and 5a+8 it will be 5a and 6a

( a is the common factor, used to bring the actual ratios in their simplest forms)

4a+8 : 5a+8 :: 5a : 6a

(5a+8)×5a = (4a+8)×6a

(i hope u know how this came up)

25a^2 + 40a = 24a^2 + 48a

25a^2 -24a^2 = 48a -40a

a^2 = 8a

a^2/a = 8

a= 8

so, a=8

so present age of ramu =4a

= 4×8

= 32 years

present age of Raghu = 5a

= 5×8

= 40 years

Mark as brainlist if you are satisfied with the answer.

And it's 100% correct!!!

thanks for the points
