Answer 1

Given :  Ashok sells his goods 50% dearer than Shankar and 20% dearer than Bishnu.

To find : How much percentage is Bishnu's goods dearer than Shankar's

Solution:

Let say Shankar  Good  Price =  S

&  Bishnu  good Price  = B

Ashok sells his goods 50% dearer than Shankar  = S + (50/100)S  = 1.5S

Ashok sells his goods 20% dearer than Bishnu = B + (20/100)B = 1.2B

=> 1.2B  = 1.5S

=>  B  = 1.25S

B - S = 0.25S

= (0.25S/S) * 100 = 25 %

Bishnu's goods dearer than Shankar's   by 25 %
