Total number of boys in college = 18 + 47 + 40 + 30 = 135; Total number of girls in college = 35 + 25 + 45 + 10 = 115 ; Required Ratio = 135 : 115 = 27 : 23
23)The following table shows the income (in Rs.) for a particular month, together with their source, in respect of 5 employees (A, B, C, D and E)
How many employees got more than a total of Rs. 10,000 as income other than salary?

Salary of A = 52000;
Other income = total - salary;
Other income of A = 66000 - 52000 = 14000;
Salary of B = 48500;
Other income of B = 59000 - 48500 = 10500;
Salary of C = 42000;
Other income of C = 52000 - 42000 = 10000;
Salary of D = 31000;
Other income of D = 40000 - 31000 = 9000;
Salary of E = 25000;
Other income of E = 31700 - 25000 = 6700;
2 employees(A and B) got more than a total of ₹10,000 as income other than salary.

Required number = 3;
3 employees(A, B and C) got more arrears than the average arrears received by all the employees.
