let GDP be 100 in 2015 then fiscal deficit is 4% so it would be 4.

Now GDP increase by 10% in 2016  so the GDP now will be 110

and fiscal deficit is 5% of it which would be 5.5

now percentage increase=(New-old)*100/old %

(5.5-4)*100/4=>1.5*100/4 this will be equal to 37.5% which is option A

Answer 1

Fiscal deficit in 2015 $ = 4\%$ of GDP in 2015

Fiscal deficit in 2016 $ = 5\%$ of GDP in 2016

GDP in 2016 $= 1.1 \times $ GDP in 2015

So, Fiscal deficit in 2016 $ = 5\%$ of $1.1 \times$ GDP in 2015 $=5.5\%$ of GDP in 2015.

So, Fiscal deficit increased from $4\%$ to $5.5\%$ of the GDP in 2015.
Percentage increase $ = \dfrac{5.5-4}{4} \times 100\%= \dfrac{300}{8}\% = 37.5\%$
