A company has three branches. Branch A has 40 employees with average monthly sales of ₹1,20,000, Branch B has 30 employees with average monthly sales of ₹1,80,000, and Branch C has 30 employees with average monthly sales of ₹1,50,000. What is the average monthly sales per employee of the company (in ₹)?
1,47,000
Total sales: \(40\times1{,}20{,}000 + 30\times1{,}80{,}000 + 30\times1{,}50{,}000 = 48{,}00{,}000+54{,}00{,}000+45{,}00{,}000 = 1{,}47{,}00{,}000\).
Total employees: \(40+30+30=100\).
Average per employee: \(\dfrac{1{,}47{,}00{,}000}{100} = 1{,}47{,}000\).
Hence, the average monthly sales per employee is ₹1,47,000.
