Question

Answer 1

Answer:

5% Increase

Step-by-step explanation:

Let the initial income , A= Rs.100

Resultant income after 30% decrease , B = A-(30% of A)

= 100-30 = Rs. 70

Final income , C = B + (50% of B)

Or C = 70 + 35 = Rs. 105

Hence %change = ((105-100)/100)*100

Or , 5% Increase

Answer 2

Step-by-step explanation:

let income be 100

decreased by 30%=100×30/100 =30

so decrease =100-30=70

increased by 50 %=70×50/100=35

so increase =70+35=105

change in income=105-100×100/100

=5×100/100= 5%

change in income =5%
