Answer 1

Answer:

45 year age of c after 5 year

Answer 2

Answer:

45 years

Step-by-step explanation:

Ages are in ratio which means they are not exact values, so let age of A, B and C as 2x, 3x and 4x respectively.

2x+3x+4x=90 (given)

9x=90

x=10

Threfore, Age of A, B and C are 20,30 and 40 respectively.

Present age of C is 40

After 5 years age of C will be 40+5=45years
