Question

If dhoni's height is 20% less than ishant's height then how much percent is ishant's height more than dhoni's

Answer 1

Let us assume Ishant's height , i =  100 units.
As per question,
Dhoni's height, d = 20% less than i = (100-20)% of i = 80% of i
                            = $\frac{80}{100}$×100
                            = 80 units
Percentage of Ishant's height more than Dhoni's height
                            = $\frac{i-d}{d}$ ×100
                            = $\frac{100-80}{80}$ ×100
                            = $\frac{20}{80}$×100
                            = $\frac{1}{4}$×100
                            = 25

Hence, Ishant's height is 25% more than Dhoni's height.
                            

Answer 2

Solution -

Let Ishant's height be 100 cm

Then Dhoni's height will be 100 - ( 20

% of 100)

= 100 - 20

Dhoni's height = 80 cm

Excess of Ishant's height over

Dhoni's height in percent

= {20/(100 - 20)} × 100

= (20/80) × 100

= 25 %

So, Ishant's height is 25 % more than

Dhoni's height.
