Question

दो संख्याओं का योग 45 है और उन अनुपात 7:8 है वह संख्या क्या होगी ​

Answer 1

Answer:

$x + y = 45 \\ \\ \frac{x}{y} = \frac{7}{8} \\ \\ x = \frac{7}{8} y \\ \\ \frac{7}{8} y + y = 45 \\ \\ \frac{15}{8} y = 45 \\ \\ y = 24 \\ x = 45 - 24 = 21$

Answer 2

Step-by-step explanation:

Let the two unknown numbers be 7x and 8x

as per the condition,

7x + 8x = 45

15x = 45

x = 45/15

x = 3

7x = 7*3 = 21

8x = 8*3 = 24
