Answer: the brother is 20 and the sister is 9
Step-by-step explanation:
29 - 11 = 18 18 divided by 2 is 9
9+11 is 20 the brothers age so the sister is 9
There are two possible answers: 72 and 90.
We can find the answer by looking at the largest number among the three of them: 18. The only multiples of 18 between 61 and 107 are 72 and 90. We can check that both numbers are also multiples of 6 and 9:
90 : 6 = 15
90 : 9 = 10
72 : 6 = 12
72 : 9 = 8
Answer with explanation:
Total number of Children = x Children
Total number of chocolates distributed = y Chocolates
If there are x children, then total number of chocolate got by children= 5 x Chocolate
Number of chocolate got by Adults= 20

Expressing the statement in terms of Equation
y = 5 x + 20 z
⇒Number of Adults =z

Answer:
21 and 30
Step-by-step explanation:
x + y = 51
x - y = 9
add the two equations and y's will cancel out
2x = 42 divide by 2
x = 21 so put 21 in for x in the top equation and solve
21 + y = 51
y = 30
