The equation from the word problem is 2(x+5)+25=140. Distribute 2 to the parentheses and get 2x+10+25=140. Combine like terms to get 2x+35=140. Subtract 35 from both sides and get 2x=105. Divide both sides by 2 and your final answer is x=52.5

Answer: Hence, the correct size of boys group is 5 and girls is 6.

Step-by-step explanation:

Since we have given that

Number of boys = 60

Number of girls = 72

We need to divide the students into gender specific groups of the largest possible size.

For this we will find "HCF of 60 and 72" which is equal to "12".

So, the correct size of each group is 12 in which number of boys would be $\dfrac{60}{12}=5$

Number of girls would be $\dfrac{72}{12}=6$

Hence, the correct size of boys group is 5 and girls is 6.
