i will give 30 points.​

Answer 1

Let one number be "x"

Then other number = (4000 - x)

ATQ,

15% of x = 25% of (4000 - x)

$\bf \implies \frac{15}{100} \times \: x = \frac{ 25}{100}(4000 - x)$

$\bf \implies 15x = 100000 - 25x$

$\bf \implies15x + 25x = 100000$

$\bf \implies40x = 100000$

$\bf \implies \: x \: = \frac{100000}{40}$

$\bf \implies \: x = 2500$

Other number = 4000 - x

= 4000 - 2500

= 1500

Hence, The numbers are 2500 and 1500

Answer 2

Let one number be "x"

Then other number = (4000 - x)

ATQ,

15% of x = 25% of (4000 - x)

\bf \implies \frac{15}{100} \times \: x = \frac{ 25}{100}(4000 - x)⟹

100

15

×x=

100

25

(4000−x)

\bf \implies 15x = 100000 - 25x⟹15x=100000−25x

\bf \implies15x + 25x = 100000⟹15x+25x=100000

\bf \implies40x = 100000⟹40x=100000

\bf \implies \: x \: = \frac{100000}{40}⟹x=

40

100000

\bf \implies \: x = 2500⟹x=2500

Other number = 4000 - x

= 4000 - 2500

= 1500

Hence, The numbers are 2500 and 1500
