Question

2. If 1/8!+1/9!=x/10! the value of x is
a) 100
b) 90
c) 95
d) 80​

Answer 1

Answer:

1/8! +1/9! = x/10!

(9! + 8!)/9! 8! = x/10!

8!(9 + 1)/9! 8! = x/10!

10/9! = x/10!

x = 10! x 10/9!

x = 10 x 9! x 10/9!

x = 10 x 10

x = 100

Option (a)

Here's the answer

2. If 1/8!+1/9!=x/10! the value of x is

a) 100

b) 90

c) 95

d) 80

$\huge{\orange{\mid{\boxed{solution}\:{\mid}}}}$

$\frac{1}{8} + \frac{1}{9} = \frac{x}{10} \\ \\ \frac{9 + 8}{72} = \frac{x}{10} \\ \\ \frac{17}{72} = \frac{x}{10} \\ \\ \frac{17}{72} \times 10 = x \\ \\ \frac{170}{72} = x$

I think there's a correction in your digits of question.....but the method would be same.....
