Answer 2

Question:-

Present age of Meenu and Mukul are in the ratio 3:4. After five years from now the ratio of their ages will be 4:5. Find their present age.

Given:-

Present age of Meenu and Mukul are in the ratio 3:4. After five years from now the ratio of their ages will be 4:5 .

Find:-

Present ages of Meenu and Mukul ?

Solution:-

{ According to given }

The ages of Meenu and Mukul are in the ratio 3:4 { before 5 year's }

Let, present age of Meenu be 3x and present age of Mukul be 4x .

Now, { after 5 years }

• Age of Meenu = 3x + 5 ..... ( 1 )
• Age of Mukul = 4x + 5 ..... ( 2 )

To Find :-

Present age's of Meena and Mukul

According to question { or given } the ratio of age's of Meena and Mukul after 5 year is 4:5 .

Hence, { from ( 1 ) & ( 2 ) }

${ \sf{ \purple{ \dashrightarrow}{ \bf{ \frac{3x + 5}{4x + 5} = \frac{4}{5} }}}}</p><p>$

${ \sf{ \purple{ \dashrightarrow}{ \bf{5 (3x + 5) =4 (4x + 5) }}}}</p><p>$

${ \sf{ \purple{ \dashrightarrow}{ \bf{ 15x + 25 = 16x + 20}}}}</p><p>$

${ \sf{ \purple{ \dashrightarrow}{ \bf{15x - 16x = 20 - 25 }}}}</p><p>$

${ \sf{ \purple{ \dashrightarrow}{ \bf{ - x = - 5 }}}}</p><p>$

${ \sf{ \purple{ \dashrightarrow}{ \bf{x = 5 }}}}</p><p>$

Put value of x in

• Age of Meenu = 3x
• Age of Meenu = 3(5)
• Age of Meenu = 15 year's

Put value of x in

• Age of Mukul = 4x
• Age of Mukul = 4(5)
• Age of Mukul = 20 year's

Hence, present age of Meenu is 15 year's and present age of Mukul is 20 year's .
