Answer 1

Let the monthly saving be Rs a and increase in saving be Rs b

Money saved in 16 months = 16a

New monthly saving = 14 ( a + b)

Money saved in 14 months when saving increased = Money saved in 16 months earlier

=> 14 ( a + b) = 16a

=> 14a + 14b = 16a

=> 14b = 2a

=> a = 7b


Now,

Increase in saving = b = a/7

Percentage of increase = Increase in saving × 100 / Original saving

= ( a / 7) × 100 / a

= 100 / 7

= 14.28 % ( approx..)

Answer 2

Let the monthly saving be Rs a and increase in saving be Rs b

Money saved in 16 months = 16a

New monthly saving = 14 ( a + b)

Money saved in 14 months when saving increased = Money saved in 16 months earlier

=> 14 ( a + b) = 16a

=> 14a + 14b = 16a

=> 14b = 2a

=> a = 7b

Now,

Increase in saving = b = a/7

Percentage of increase = Increase in saving × 100 / Original saving

= ( a / 7) × 100 / a

= 100 / 7

= 14.28 % ( approx..)
