Answer 1

Step-by-step explanation:

John is 7 years younger than Ahmad. If the sum of their ages is 38, how old are the three boys? B=9 AGE OF BOBBY. A=2*9=18 AGE OF AHMAD.

Answer 2

$\huge\bold{\mathtt{\purple{ A{\pink{ N{\green{ S{\blue{ W{\red{ E{\orange{ R}}}}}}}}}}}}}$

INFORMATION BEFORE STARTING THE SOLUTION :

Let Age of Bobby be x

∴ Age of Ahmed is x+9

and Age of John is (x+9)-7

----------------------------------------------------

Now,

x + (x+9) + [(x+9)-7] = 38

3x + 18 - 7 = 38

3x + 11 = 38

3x = 38 - 11

x = $\sf{\frac{27}{3}}$

x = 9

So, Bobby is 9 years old

Now, look at the information I wrote in the beginning.... Using that information we find out the age of Ahmed and John

Age of Ahmed = 9 + 9 = 18

Age of John = 18 - 7 = 11

∴ The age of Bobby, Ahmed and John is 9, 18 and 11 respectively
