C.	15%	D.	16 2/3%
E.	20%

Answer and Explanation

Answer:16 2/3%

Explanation:
let his monthly income be Rs. x
Original savings = Rs. 10/100 x
New savings 10/100x + 20/100(10/100 x) = Rs. 12/100x
Original expenditure = x – 10/100 x = Rs. 90/100x
New expenditure
90/100x – 20/100(90x/100) =Rs. 72/100 x
Required percentage = 12/100x / 72/100x (100) = 16 2/3%
