expenditure is increased by 20%. His savings:​

Answer 1

Answer:

rs.42.1

Step-by-step explanation:

let his income be 100.

a spends 65.

he is left with 35.

his new income=120.1

his new expenditure=20% of65

=20/100×65

=13

new expenditure=65+13=78

his savings=120.1-78=42.1

Answer 2

Let income be ₹100

Expenses = 65%

Savings = 100%-65% = 35%

Income increased = 120.1

Expenses increases by 20%, ie.

65×120/100 = 78

Savings = 120.1-78 = 42.1

% of savings = 42.1/120.1×100 = 35% (approx)

No change in percentage of savings

35% itself.
