His age is 70 years. We can use the information to form an equation and then solve it. The equation would be 400 - 3x = 190 and then when you solve it, you get 70.

Answer:

Let's have x be his age.

He said that 400:

400 reduced by 3 times my age:

400 − 3x

is 190:

=> 400 − 3x = 190

=> 3x = 400−190

=> x= 210

=> 210÷3

=> 70

His age = 70
