====$138600.

Answer 2

In these questions, there are two parts, First is the original quantity and second part is the % increase in the quantity. The final quantity will be the sum of original quantity and % increase quantity
Let us assume the original salary is y, then
y + 10% of y   = New salary= 154000
y+ 10y/100=154000
11y/10=154000
y=1540000/11= Rs 140000

Hope it Helps...
