Question

present Age of nisha and bandhu are the ratio4:5eight year from now ratio of their ages will be 5:6.find the present ages.

Answer 1

Nisha age=>4x
Bandhu age=>5x

→Eight year from now
4x+8/5x+8=5/6
6(4x+8)=5(5x+8)
24x+48=25x+40
48-40=25x-24x
8=x

→Present age
Nisha(4x)=4×8=>32
Bandhu(5x)=>5×8=>40

Answer 2

hey mate !!

here is your answer !!


in the questions given the present ratios of the nisha and bandhu are in the ratios forms 4:5.

let be the present age of nisha be 4x.

and ,

let be the present age of bandhu be 5x.

now according to questions

eight year from now ratio of their ages will be 5:6.

it's meant

$\frac{4x + 8}{5x + 8} = \frac{5}{6} \\ \\ cross \: multiplication \: in \\the \: given \: form . \\ \\ {6 \times (4x + 8)} = {5 \times (5x + 8)} \\ \\ 24x + 48 = 25x + 40 \\ \\ 48 - 40 = 25x - 24x \\ \\ 8 = x$

here we find the present age of nisha and bandhu.

putting the values of x in ratios.

nisha equal to 4x equal to 4 × 8 = 32

bandhu equal to 5x equal to 5 ×8 = 40


therefore the present age of nisha is equal to 32 year and bandhu age equal to 40 year.


hope it's help you
