Answer 1

Answer:

Solution:

Option(B) is correct

Savings in 2001:

=1,20,000×20100=24,000

Savings in 2002:

=2,40,000×108360=72,000

⇒ % Increase in Savings:

=48,00024,000×100

=200%

Amount spent on transport in 2001:

=1,20,000×5100

=6,000

Amount spent on transport in 2002:

=2,40,000×36360

=24,000

⇒ % Increase in the amount spent on transport:

=18,0006,000×100

=300%

The percentage point difference:

=200−300

=−100

⇒ Less by 100 percentage points.

Alternate method:

Total salary in 2002 was increased by 100%

Share of saving in 2002 is 30%, when the total salary increased by 100%, share of saving will also be doubled i.e., 60% similarly, the share of transport in 2002 is 20%.

Percentage increase in saving is 20% to 60% i.e., 200%

Percentage increase in transport is 10% to 20% i.e., 100%

Difference in percentage is 100% points.
