Answer 1

Answer:

6x+8: 7x+8=8:9

56x+64=54x+72

2x=8

x=4

6x+12: 7x+12

24+12=28+12

36:40

9:10

Answer 2

$\huge{\underline{\underline{\mathbb{\pink{ANSWER}}}}}$

Let the present ages of Sushma and Krishna be 6x and 7x respectively.

Therefore,

$\frac{6x + 8}{7x + 8} = \frac{8}{9}$

$x = \frac{8}{2} = 4$

Required Ratio :-

$\frac{6 \times 4 + 12}{7 \times 4 + 12} = \frac{36}{40}$

= 9:10
