Question

divide rupees 90 in the ratio 2:4​

Answer 1

$let \: 2 \ratio4 \\ = > 2x \ratio4x$

$2x + 4x = 90 \\ = > 6x = 90 \\ = > x = \frac{90}{6} \\ = > x = 15$

$2x = 15 \times 2 = > 30 \\ 4x = 4 \times 15 = > 60$

Answer 2

Answer:

90 into 2:4

let x be 1 unit

we need to devide 90 into 2x and 4x

2x+4x = 90

6x     = 90

   x    = 90/6

    x  = 15

2x = 30

4x = 60

then 90 rupees in the ratio 2:4 is 30:60

90 into 5:4

5x+4x=90

 9x   = 90

    x  = 10

5x = 50

4x=40

then 90 rupees in the ratio 5:4 is 50:40
