Question

The sum of age of four brothers is 56 years. Difference of their age is 4 years equality. Find the age of elder brother.

Answer 1

Answer:

20 years

Step-by-step explanation:

let x be the age of smallest brother

so (x+4), (x+8), (x+12) will be the ages of remaining brothers with difference of 4 years each respectively.

given

x + (x+4) + (x+8) + (x+12) = 56

4*x + 24 = 56

4*x = 32

x = 8

therefore elder brothers age will be

x+12= 8+12= 20 years
