Question

(3/7)^4 multiple (7/3)^2 multiple (1/7)^-2

Answer 1

Step-by-step explanation:

Let the salary before the increment be Rs.100. Then,

Increase in salary =Rs.10

∴ Increased salary =Rs.(100+10)=Rs.110

If increased salary is Rs. 110, original salary =Rs.100

If increased salary is Rs. 154000, original salary =Rs.(110100×154000)=Rs.140000

Hence, the salary of the man before increment was Rs.140000.
