- 10%
- 25%

**Answer: (1) 37.5%**

**Explanation:-**

Let the income of a man be Rs.X

A man spends 75% of his income,

Then, Saving = X – X x 75/100

= X – 3 X/ 4

= X / 4

His income is increased by 20%

Then, the income = X x 120/100

= 6 X/5

Increased his expenditure 10 %

Then, 3 X x 110/4 x 100

= 33 X /40

New Saving = 6 X / 5 – 33 X/ 40

= (8 x 6 X – 33 X)/40

= (48 X – 33 X)/40

= 15 X /40 = 37 .5

Saving increased by 37.5 %.

Hence, the answer is (1) 37.5%.

2. 50%

exp

% increase= 12.5/25*100
