Dear CCI members, plz guide me to solve these problems from ICAI Book.
1. If the A.M and H.M for two numbers are 5 and 302 respectively then what is GM ? Ans: 4
2. The Average Salary of a group of unskilled workers us Rs.10,000 and that of a group of skilled workers in Rs.15000. If the Combined salary is Rs.12000, then what is the percentage of skilled workers? Ans: 40%
2. no skilled person be x, then no of unskilled persons = 100-x,
now, avg = total salary/ no of persons
10000(100-x)+15000x / 100 = 12000
1000000-10000x+15000x=1200000
5000x=200000
x=40
skilled workers=40%
