Answer:
The son is 20 and a half years old.
The father is 36 and a half years old.
Step-by-step explanation:
We can solve this easily by turning it into an equation.
Let the mans age be y and the fathers age be x.
y+x=57
x=y+16
We can use the substitution method to solve for the first equation.
y+(y+16)=57
Now we only have one variable to solve for. Add like terms.
2y+16=57
Subtract 16 on both sides.
2y=41
Divide both sides by 2 to isolate y.
y=20.5
Now substitute 20.5 for y to solve for x.
20.5+x=57
Subtract 20.5 from both sides.
x=36.5

150 = 12
150 +150 = 300 which = 24
150 + 150 + 150 = 450 which =36
the remaining 50 is 12 ÷ 3, so 4. 36 + 4 = 40.

Answer:
Breadth = 15 cm
Step-by-step explanation:
Area = length x breadth
315 = 21 x breadth
[ dividing both sides by 21 ]
25% = 0.25
124 x 0.25 = 31
31 students bought their lunch.
Part = 31
Percent = 25%
Whole = 124
