Average Practice Test 4

Total monthly salary of all the employees = Rs (2,400 × 12) = Rs 28,800
Total monthly salary of the senior level employees = Rs (1,200 × 5) = Rs 6,000
Total monthly salary of the junior level employees = Rs (1,000 × 5) = Rs 5,0001∴ Average monthly salary of the remaining employees $=\frac{28,800-\left(6,000+5,000\right)}{2}$
$=\frac{28,800-11,000}{2}$ $=\frac{17,800}{2}$ = Rs 8,900
