Step-by-step explanation:
Given : Mrs.Sauchita earns Rs.11000 per month .She spends 85% of the amount and saves the rest.
She spends total money = 85% of 11000 = 85 × 11000100 = 85 × 110 = 9350
Amount she saved = 11000 - 9350 = Rs . 1650
On 1st January her salary was increased by 20%. So
New salary = 11000 + 20% of 11000 = 11000 + 20 × 11000100 = 11000 + 20 × 110 = 11000 + 2200 = Rs . 13200
She now increased her expense to 87% of her salary , So
She spends total money = 87% of 13200 = 87 × 13200100 = 87× 132 = 11484
Amount she saved = 13200 - 11484 = Rs . 1716
She saved more money by 1716 - 1650 = Rs 66 ( Ans )
