The ratio of K’s and M’s ages is 4: 5. If the difference between the present age of M and the age of K, 5 years hence is 3 years, then what is the difference and total of present ages of K and M? Explanation:
Let the present ages be K, M

Given K/M = 4/5

5K - 4M = 0 (1)

Also given that,

M - (K + 5) = 3

M - K = 8 (2)

Then, by solving (1) & (2)

M = 40 yrs and K = 32 yrs now explain how we got m=40 and k=32 from equation on 1 and 2
Hence, Total of ages = 40 + 32 = 72 yrs

Difference of ages = 40 - 32 = 8 yrs.
now explain how we got m=40 and k=32 from equation on 1 and 2 step by step
