Answer is D
10% boys = 20% girls..... For eg. There are hundred boys in the class, now a ten percent of them would be 10 boys, if ten boys is equal to 20% of the number of girls, then the total number of girls(x) =
20/100 (x) = 10
=>x=50
Thus the ratio of boys to girls is 100/50 or 2:1

Understanding the Question:
In the given scenario, 10% of boys are equal in number to 1/5th of the girls. We need to find the ratio of boys to girls in the school.
Solution:
Step 1: Assign Variables
Let's assume:
- Number of boys = B
- Number of girls = G
Step 2: Given Information
According to the question:
- 10% of boys = 1/5 * girls
Step 3: Convert Percentages to Fractions
10% of boys can be written as 0.10B
1/5 of girls can be written as 1/5 * G
Step 4: Equation Setup
0.10B = 1/5 * G
Step 5: Solve for B and G
0.10B = 1/5 * G
0.10B = 0.20G (since 1/5 is equal to 0.20)
B = 2G
Step 6: Ratio of Boys to Girls
Now that we have found B in terms of G, the ratio of boys to girls is:
B:G = 2:1
Therefore, the correct answer is:
(d) 2:1
