​

Answer 1

Step-by-step explanation:

Consider A’s and B's age after 10 years will be 4x and 5x.

so their present age should be 4x — 10 for A

and 5x — 10 for B.

sum of their present age is 70 which mean:

(4x — 10) + (5x — 10) = 70

9x — 20 = 70

x = 10

present age of A = 4x — 10

which is 40 — 10= 30
