Answers
Answer:
Step-by-step explanation:
Let' say her expenditure is 300 rs and savings are 200 rs.
Total income = 500 rs
New income increase = 500 *10/100 = 50
New income = 500+50 = 550 rupees
New expenditure increase= 300 * 12/100 = 36 rupees.
New expenditure= 300 + 36= 336
New savings = 550- 336 = 214 rupees
Percentage increase in savings =
= New savings - old savings / old savings * 100
= 214 - 200/200 * 100
= 14/200 * 100
= 7 % increase
Therefore, 7% is the increase in her savings
Answer:
Option A is correct.
Step-by-step explanation:
Given:
Ratio of saving and Expenditure = 3 : 2
Percentage increase in Income = 10%
Percentage increase in Expenditure = 12%
To find: Percentage Increase in the Saving
Let the Earning = Rs. 100
⇒ Expenditure = Rs. 60
⇒ Saving = Rs. 40
New income = 100 + 10/100 × 100 = Rs. 110
New Expenditure = 60 + 12/100 × 60 = Rs. 67.2
New saving = 110 - 67.2 = Rs. 42.8
Percentage increase in saving = (42.8 - 40)/40 × 100 = 7 %
Therefore, Option A is correct.
